Sir. I really really want to thank you for that well well detailed video. My 90 5.0 was having literally those problems you mentioned. It was just a stock rebuild engine with just a B303 cam and valve springs. I was dealing with idle and timing problems for a year until I saw your video yesterday and did exactly what you said in the video. Now thanks to you I’m back on the road. Thank you 😊.

If you have a crossfire setup on a modified engine, would you increase or decrease the amount of water pulled? If I’m at 6 the idle is rough, if I decrease it, it smooths out. I hooked up a vacuum gauge at the manifold and the needle bounces at 6 but levels out when that is adjusted down.

So if my battery dies and I have all of this properly set do I have to unplug the IAC and the spout connector when I put my new battery in to get everything to run properly again? Ive also seen a lot of videos about doing a base idle reset. I've always had good luck doing that and clearing up most of my surging issues in any of the foxes that I've put together. I never have done it this way and I'm just curious because now this seems a lot more sensible obviously and your car sounded very clean

Hey Joe crossfire injection question. 82 Corvette idle surges from almost quitting 450 RPM to 800 and continues to do that till it warms up and then it runs great. New temperature sensor in the front of the engine. New idle air control valves and cleaned out the receptacle. New fuel pump and filter.

I have an 84 Corvette, manual transmission. What ECM do you recommend?

Hey Joe! Was wondering if I could get ur help with my 82 comaro with crossfire injection! Maybe you can point me to the right direction?

Are you interested in doing my 84 Corvette with a high performance V8 under the Crossfire? You could make several very cool videos!

so i just picked a 'new' reman box from O'Reilies over the weekend for my 2000 s10, it helped ALOT... but still had a massive dead zone from 11-1 o clock in the steering wheel i finally figured out where it was this evening watching the linkage and everything while under the truck and twisting in the steering shaft... the freakin sector shaft was deflecting nearly .060 side-to-side.... took nearly a half turn of tightening up the shaft to finally bring it into tolerance and stop the dead zone, finally does what its supposed to when you turn the steering wheel it instantly responds instead of having to move through the dead space before it started moving

Definitely different and then there is Dakota Digital.

Nice video. Some of us have been preaching SPOUT out when doing base idle reset for a many years now online - just need to find us. One thing you did not mention at all is the learn steps of the base idle reset. The computer needs to be reset after setting the idle is adjusted as you described (disconnect battery for a few minutes) and retaught what idle is and loads it will experience. That's why you do the 2 mins running of no load (everything off) then 2 mins of the engine off, then 2 mins of every load you can put on the engine (A/C, lights, blower fan, electric fans (if you have them) so that the computer will learn what maximum engine at idle load could be and it can learn an idle strategy to run smooth. Then 2 more mins of engine off. Now you are set with your idle tuning.

You seem to be very knowledgeable with the crossfire injection and I hope you can maybe answer this question. 82 Corvette ran great and then one day I started it and the idle is a erratic. Going from 500 RPM to 900, up-and-down and sometimes quits Went down. Once warmed up, the car runs great.

What is the Al/dl port or jumper

Were the steps ever shared? Great video!

Everything I have read says to unhook the IAC as it will try to adjust idle.

I wonder if it is a good idea to use WD 40 to lubricate the thread, after cleaning.

I understand why people just adjust the easier nut. If I've gotta remove the damn box to do this, I'm just replacing it.

Great vid man, as an 80s kid I chased this problem through many cam swaps.

Traction control is complete aids. Both my parents' chevy sonic and toyota avensis verso traction controls went bad. In the Toyota had to emergency on the side and restart car to get out of traction control killing all power to the wheels. The fact even Toyotas can't keep traction control working right for even 10 years says a lot.

Would too much pre load effect power steering pressure? Thanks

Joe, I was wondering if you still were looking for a crossfire set up as i have an 83 camaro crossfire all still intact and runs. Maybe we could trade your single tbi setup for my setup?

Hey Joe I have cFI injection questions!! It's for an 84 corvette all stock.... I've heard ghost stories of bored out throttle bodies. Do you know anything about this myth?

That’s a nice clean fox man, congrats! I just got my first fox (89 GT w/T5) this summer and I love it. That 5.0 sounds and feels amazing, especially with flow master. I’ll be putting on some GT40 heads and a cobra upper/lower with a trick flow stage 1 cam. Anyways, great car and have fun with it!!

Holy crap thank you. So much appreciation right now. Right now on mine that pitman shaft adjust is all the way down flush with the nut and theres so much play in the wheel. I was about ready to buy a totally new box.

Did 82 offer carpeted floor mats and a privacy screen for trunks ? Camaro in 82 did not 1982 is my favorite because of those seats . 1983 i like for the 4 speed Auto Trans

The best looking car was the 1984 Recaro Edition. L69 with the WS6.

Are you in AZ? i have 1982 Corvette that need you, how can i contact you? thank you

I just listened to the last 5 minutes and now I feel guilty for being a lazy ass and adjusting the wrong one. Stupid HOA. People already think I’m Fred Sanford with the amount of old cars I have.

Did these throttle bodies have a mystery teflon coating around/on the butterfly that's likely long gone after all these years?

Do you add tension to the spring to increase the fout pressure (clockwise from the bottom) or decrease spring tension to increase pressure?

I also used IAC valve off the crossfire injection style, is that okay? I’m only asking because got my whole car together got it timed 6 degrees btdc and fuel wants to spray until start up then stops spraying

Do you think my car isn’t starting because I’m you a different throttle position sensor? I’m using the one off the 88 pickup and my cars an 82

Where i can buy this water manometer? I have 3 crossfire trans am, and i Need it to adjust and Sync

wow that was INCREDIBLE. FINALLY someone doing it the RIGHT WAY! Worked on a 03 Chevy S10 (a little different but the same therory) b/c I couldn't find the right ratio anywhere so decided to work on the original (service manual pretty much backed up EVERYTHING you said). Even found out I had an old post-type torque wrench in My Dad's old toolbox. THANK YOU!! LIKE NEW results!!

Can you show me where you ran ur vacuum lines?

Hi Joe I’m back, do got it all together and the injectors seem to prime the car and will run for quick second then quit spraying and died. Any suggestions on what could be going on?

Can you post the link of that plat you put on the Iac

What kinda bracket did you use for the throttle cable etc.

So I got the intake on, but the middle 6 bolts don’t seem to want to grab… ?

Just started the project today! So I have another question, there’s 2 of the idle control valves, where did you run both? Or did you wire them in together

So I’m trying do this set up also on my 82 comaro I have and idk if they make an intake I can swap over to tbi, I’m just trying to get the right parts. Please help

Beautiful car!!!

For clarity, is this cold or at operating temp when doing this procedure ?

Thanks for the video. Quick question I have an 84 pontiac firebird 305 would you know what new years have similar parts as fuel sending unit

I am curious, when a single line of the mono meter is connected, why doesn’t it get sucked all the way like a straw? Do you have to cover the other end of the manometer?

Just daily a Big Block V8 Chevelle and your good to go. Haha

What’s the tool for removing the plunger?

Thanks for posting this video. I am converting my 83 LU5 trans am ECM to a 7747 out of a 1990 silverado. My transmission is automatic 700R4. I have the plugs for the 7747, so I am going to solder them in. Would you be willing to send me the pinouts for the 7747 ECM? Great videos!

Are you still using the egr valve?

Fuck these things suck!!!!! I had nothing but headaches with my 84 corvette with crossfire!! Ended up boring and stroking it out! Slapped an LS into it!

what is maximum ignition retard that the stock computer can induce, (afterwards when timing spout is re-installed) computer desperately trying to get to 700 rpm target idle speed, when the thumper cam is at 950 rpm? lol
