I got question here. My car really hesitate when i accelerate for overtaking but running well if normal driving. I find that if removed maf sensor connector my car hesitation gone. But engine check will appear and car bogging while in idle. Is this my maf sensor faulty?
If the car is running better without the maf sensor plugged in, it is very likely the sensor is sending bad readings and should be tested and possibly replaced.
Question: Must the MAF always be disconnected before cleaning? Looks like the previous owner of my car glued on the harness connector for some reason, probably the clip is broken. I'd hate to pry it open and possibly make things worse. I'm thinking to take out the MAF and spray it while it's still connected.
This will not necessarily get rid of the check engine light, what one needs to do after cleaning the sensor is remove the negative power cable on the battery for 30 minutes to reset the computer
You're not blasting it with the MAF Sensor cleaner as you should . Hold it at different angles when spraying and shake it in between . I let it dry inside at room temperature for two hours before reinstalling .
Thanks for the comment! The consensus I've seen is around 10-15 bursts on the sensor. I would not want to shake the sensor, unless you mean the can? And definitely can't hurt to let it sit for 2 hours, I've always had positive results with at least 5 min, some say it is dry after 1 min. Can't hurt to be sure though!
It’s dry enough after a minute. The solvents used are highly volatile. 2 hrs is utterly non-sensical. Anything left in the housing will disappear in the rush of filtered air being sucked in at high velocity through the intake.
And btw, just a few short shots is enough to clean it. Any more is completely pointless waste. CRC themselves actually say just a few sprays. You can see the sensor clean after a couple of shots.
Thanks for this tutorial it fixed my starting problem
Love to hear it!
Awesome, exactly what I needed to know, cheers!
Glad to hear!
I would like to note that the CRC bottle specifically states do NOT use on ‘some’ 2006 Toyota / Lexus / Mitsubishi vehicles

Hey! Thats should no problem. There is probably a minute chance of short circuit so to be safe I would disconnect the battery before you do if!

@@cruisinwithgreg I just slightly shake it
