do i havce to have a feeler gauge?

Yeah, 2... a .5mm and a .9mm for 7MGTE's. Just for anyone who's reading, a .4mm and .75mm for 7MGE's. Check out this link for the terminals to measure from and the proper resistance values.

Whats an AFM and I/C and IACV?

im having similar issues..
sometimes when i turn on my car itll start out fine at 1000rpm
then drop down to 500-600 or lower.. and it will just bounce back and forth.. high low high low.. or itll just die after a couple of bounces..

then if i shut down my car then start it back up again itll be fine..

also other times when im applying my brakes and come to a stop and my car is in neutral my rpms will drop and act as if its about to die then jump back up and begin to bounce.. or sometimes just die...

been wanting some of my friends to look at my car.. i know a few are pretty good with cars.. but most dont know much bout my supra.. a couple of them are cert. mechanics but usually too busy to actually diag my car.. suckss..



1989 Supra MK3 7M-GTE

An AFM is the air flow meter.

I/C is intercooler.

IACV is idle air control valve.


If/when i do fix my problem i'll let you know lol.

If your mechanic friend comes through and fixes it, let me know too.


Btw did you pull any codes?

i did the simple test with a paper clip into the diag port and code 52 knock sensor .. but thats all that showed up..

screw should be ALL THE WAY CLOSED if you have to have it open then there is another issue your trying to compensate for. your just gonna cause more problems.

fix your nock sensor... why do people like you always think that it's not important and it must be another problem? the nock sensor can cause many issue up to engine failure. once you fix the code, if the problem is still present then move on to the next possibility. it's called trouble shooting. use your critical thinking skill man. if you start skipping things your going to have a world of problems.

"been wanting some of my friends to look at my car.. i know a few are pretty good with cars.. but most dont know much bout my supra.. a couple of them are cert. mechanics but usually too busy to actually diag my car.. suckss.."

if i knew how to get to it id do it, and if i knew i wouldnt be waitin for some buddies of mine to look at my car...

i know where the knock sensor is located but im not that knowledgable about cars yet to just take apart everything to get to the knock sensor and fix/replace it.

i never said its not important.. i dont think anyone on this thread has said that it wasnt important..

seems like your getting a little heated shiftysupra.. need to relax man.:dance:

Amen to that... This forum will be alot more helpful to everyone if people would stop trying to diss and actually help each other...

Anyway, back on topic...

Kevin! You get that TPS checked yet? Been wondering how those results turned out...

Not yet buddy, i'll post up when i do.

Yes.. helpful is good. dissing is bad.. liek the other forums.. u get a few moderators who flame you if you ask a "stupid" question.. or dont "search" even though short words like "Tps" or "iacv" dont work.
