Great help. Waiting for my new Throttle Body from the U.K. as none available in Australia. Also fitted a shield that bolts under the ECU to protect it from the engine heat; Thanks for your help, ( always needed ). I hope my results are as successful as yours. Best regards. Colin.
My pleasure. I really hope your results are the same as mine and your car is back to running well. I know the supply chain is really screwed up now hopefully you get your part quickly. Thanks for watching and have a great day!!
@@4kays160 Yes, it was quite an easy job, I also fitted the ECU insulator which helps keep it cool. Never had any problems until a week ago when I got a (check engine light) which I solved with my reader! But overall the car has been giving better mileage and never fails to start. I hope that helps?
@@ColinPrince good to know, i might just look into replacing the whole throttle body then.. im in australia too, so hopefully i can find one, as im new to saab's
@@4kays160 Make sure that you buy a genuine Saab part. Sometimes you are shipped parts supposedly genuine but are actually Chinese and they dont do so well! I’m in Mission Beach, where are you located, as there is a supplier in Melbourne and one in Perth, I believe a couple of suppliers have retired recently! That’s why I sent to the U.K. because if they don’t have a part in stock, they have it sent over from Sweden and are always super helpful.
I own a 2016 genesis coupe 3.8. I recently installed a true cold air intake. The car drives completely fine under normal circumstances, but when I downshift and try to wide open throttle above 3500rpms, the car goes into limp mode and throws this exact code. Did the increase in air break my throttle body? Car drove completely fine before the installation.
On the old TB, notice the hollow region at bottom with the knife thin mating face at throttle bore wall to gasket? The throttle you removed was for a naturally aspirated engine, not the version made for a turbocharged engine. The turbo version has a thick gasket mating surface right at the throttle bore wall, same as around the other mounting gasket interface areas.
@@caractacusbrittania7442 Regardless, that throttle body that you show is for naturally aspirated engines. Chevy Malibu and others use it. That’s not a Saab 9-3 OEM TB.
No it wasn't. The n/a GM cars the flange where the hose on has no lip. Boosted cars have a lip to help ensure the pipe remains on. Other wise n/a and boosted they are identical apart from that bead. ( Z22SE and B207R )
Did it feel like a bad head gasket when you were having these shuttering and poor symptoms with performance? I have the same code and it has old gas in it, so it could be a bad throttle body but my first concern was bad head gasket. Has the repair been good since the publish? Thanks!
@@TheHunterGatherer thanks for the reply, sounds like I am fucked…did the car work for a few months after repair or shortly after (within a month) it still had issues?
I enjoyed your video. However, my 2006 93. Does the same thing, but only After the cars warmed up. I did not see your temperature gages go up very high. Does it still have problems? When its warm? I had my ECM rebuilt and it seemed to work fine and then it started it all over again.
It seems a lot of issue with the connector, did you try to clean the connector before decide to change the throttle body? My car just pop up this code and still trying to fix it.
Thank you for this. Very helpful. A question: Have you had any more trouble with code P0638 or has changing the throttle body permanently fixed the problem? Kind regards Barry.
Hi, I’ve had no problems with p0638. My code is front bank throttle, I can’t remember the number, even though I’ve seen it 100 times. I would recommend changing the Throttle Body, but genuine Saab parts, trust me, I tried two aftermarket units and literally dumped them, a total loss!
I have this exact code, p0638 is a code for connector H2 something under the battery box its a multi pin plug, ive been told to clean out that connector really good and plug it back in , and follow the wiring both ways back from the plug to make sure there not rotted or coroded or pulled out of a plug end or shorting out first.. i have a proper code reader scanner and code eraser obd2 handtool and p0638 is the code im getting too, if you google that code, it tells you its the connector im talking about, so i have a feeling people replacing multiple throttle bodys might have had dodgy wiring and the voltage difference was the wiring leak or plug resistance, so id suggest checking that plug and clean it up, clean all the pins inside good, then check the wires are good still, clear all your codes in the car, and try and see if its fixed or not, before getting a throttle body.. ive heard of the wiring being brittle from heat and swapping out that loom section fixed it...
@@4kays160 The one thing that you’ve already learned is that a problem with a Saab that shows up on a reader can be totally unrelated to the problem. They seem to have a number of connections wired up to the same wiring loom connector. This gives you a false reading on the code reader. I’ve had a couple of issues that are related to a part of the car that proves to be unrelated to the real issue and unless you are aware of the relationship, you can be working on a problem that doesn’t need fixing, I recently went through an issue where that was the case, but I’ll definitely take a peek under the battery and see if I have a build up of dirt that could be the cause of all of my problems! Thanks so much for the heads up. Colin.
@@ColinPrince yeah no worries, its actuall common on alot of cars to send a fault up a loom earth and the electrics go haywire.. i was more saying to the other guy who was asking about his code p0638, as thats my exact code too, and ive gone into the saab error codes and its saying its that connection, and it also says that when that messes up or has a split that could be the voltage difference trigger the throttle body to move out of range ... i reset my codes, and turned of limp mode , and it hasnt done it again my throttle is acting fine now, but i still have the code come back the car just drives fine? And i had a look earlier next to my battery box, and i could see weird wiring straight away that looks like speaker cable and all sorts under my battery box, and my headlights have some strange dodgy wiring on them too.. so with any luck if i rewire it all to factory thats hopefully what is triggering that fault code?.. if not well ill look for a throttle body, likely call the place at Melbourne you recomended..
Hey brotha , so I have the same issue. I usually clear the code and run it but has been running rough. I have changed the Throttle body 2 times and no luck… I have read on forums it’s because some connector H42-2 that need to be re pinned (which I don’t now how to do) and to be cleaned i guess. I think the connector is under the battery and I tried to clean it and hook back up but still having the same issue …
I'm struggling a bit to understand exactly which/where the H42-2 connector. There isn't anything under the battery. In terms of the pins, what am I looking for?
I have same exact color car but mine 2005. And today. It started loosing power and it throwing same code. It isn't cheap. On eBay it is. I found a O'Reilly's for a little under 300
Thank you soo much this shaved me from taking it to my home town mechanic who isnt cheap ..i owe you one man
No problem brother. Glad to help. I hope it works out!
@@TheHunterGatherer ill let you know im going to try and fix it myself today 🔧 🔨 🔧 🔨
@@edgarsoccer6did it work? Im about to buy one as mine is acting crazy today, and saying throttle position codes
@4kays160 for a while it did but i just sold the car a few months ago too much of a hassle

Saab did not make a naturally aspirated 93 NG.....
They were all turbo, including the v6, the tid and the ttid diesels.

Hola!, de que modelo es el cuerpo de aceleracion que compras , es gm pero como lo pido ?
I think You have a shot wheel bearing (from the sound of it). Either that or warped brake discs.
I'm thinking the tires might be cupped, need balanced or a bearing. Good catch!
Tips from Sweden, Don’t press on the gas hard when the engine’s cold.😃
Great tip!
Same thing is happening to my car even is a p0122 and p0223 the throttle position sensor goes out doing it this weekend
How did it go?
Link to new part? Same issue here!!

It went well for a while, but I believe it ended up being the head gasket. We no longer have the vehicle. Ford should've done the right thing.

Dude trust me it was the throttle body that went bad because due to high mileage I'm going through the same thing have the same code
Thank you for the vid, glad it solved the problem.
Thanks for watching. I'm glad too!
What about the gasket
It seems a lot of issue with the connector, did you try to clean the connector before decide to change the throttle body? My car just pop up this code and still trying to fix it.
I sprayed contact cleaner on it a couple months ago. I hope it works out for you!
@@TheHunterGatherer Thanks, if you have cleaned and it is still need to change the throttle body. I will go ahead replace it.
You should try to clean yours first. Sounds like you know what you're doing.

Anyone have advice for when you get the P0638 code and you have replaced the throttle body several times . Idk if it is the ECM
Clean the pins on the connector. A lot of forums are claiming that to be a common issue. "H42-2 gray connector."
Everything im reading says a throttle body doesnt fix the problem. Most likely always an ecu problem
@@anthonym2277 it does fix it for a little while.... But I did just end up changing the ecu. You might be on the right track.
Have u ever had a steering lock malfunction in the dash board?
Not yet
Hey Steven just push the key a little hard and make sure the buttons face away from you
Hey, i have the same code in mine 08 93 how going after that job before I change my.
I hope the video helps and you can get it fixed!
me too man
What was the result with you, did this fix your 93?
Do you need to reprogram or its just plug n play
Plug and play.
Plug and play.

You get off Pat. U traded for the Toyota
