btwilson86 · 08-17-2009, 08:18 PM

Have you checked that tps yet? How far off was it, or was it dialed in correctly?

not yet. I need to go get some new feeler gauges when i have some free time this week. i am assuming i just adjust it following the tsrm?

btwilson86 · 08-18-2009, 03:01 AM

Yup. It's probably one of the easier things to do on these cars... Just have to check resistance 4 times, and if it's not in spec loosen the screw and rotate until it is.

do i havce to have a feeler gauge?

btwilson86 · 08-18-2009, 03:25 AM

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..

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?

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.
