Ok. Ugh this is getting really frustrating. Free supra anyone? lol

Could this be a knock sensor problem?

The TPS is not out of adjustment, I've checked that. Why are you telling me to plug the AFM in? lol, its been plugged in this whole time, not sure where you got the idea it wasn't.. And I have this weird feeling JJ knows exactly whats wrong with my car but he's just not going to tell me... lol UGH

Ok, more news. I just tested the VSV "high temp line pressure up system" And its shot. I have no idea if that being bad would cause this problem or not?? The TSRM says to check for Continuity between each post on the VSV, should have continuity and read 30-50 Ohms, however, mine read nothing and...

Thanks for the picture of the TPS lol.. I have a TSRM book right in front of me. The TPS tests checked out just fine from my understanding. VTA - E2 = .70 IDL - E2 = .11 VTA - E2 = 4.60 VC - E2 = 6.59 In Ohms. I check the plug for the TPS for volts. top connector was at 4.98 volts...

Is what is confusing me is why will the car rev just fine while in park, but when its in drive it wont go over 1500 RPM.

I counted the code several times, it was code 31. not 41. And if the TPS was totally shot, not just out of adjustment, would it even throw a code? Someone had told me the TPS code only pops up when its out of adjustment. I unplugged the TPS just to see what would happen. The car still ran but...

I reset the computer for a while. Then put the new AFM on. Car still had a hard time staying running at first, but after revving it for a while it would stay idling on its own. I took the car out for a quick drive and it still wont go past 1500 RPM's. The car shifts into higher gears really...

ok, the time you've been waiting for. I got the new AFM today and put it on the car... and it didn't change a single thing. So now what should I be looking into??

Sure glad I'm just talking to myself here... this forum has really gone down hill.

Bought a new battery today. Turns out the one that was in the car from when I got it doesn't even have enough cranking amps for a supra lol. The car will fire right up now, but still having the issue running... I think I'm done messing with it till the AFM comes in. I have no other leads than to...

ok jumped the car today got it running. While I have the car in park it will free rev all the way to redline. However, when I took it for a drive the car only would go to 1500 RPM then it sputtered and bogs and the car died. I tried to restart the car and it was totally dead, no power. had to...

And I have a friend shipping me an AFM to try out. something that's really weird is that when the car is in Park I can rev it up. But when I'm actually driving it the RPMs wont go past a certain point and the Auto shifts through the gears really quickly at very low RPMs

I've looked over wiring and didn't see anything wrong. Also I have checked the intercooler system about 5 times now.

Anyone? I still can't find the issue.

For 50k they better go ahead and install a metal head gasket and ARP studs for me!! lol

A few more things I've noticed. I had to jump my car to start it, the battery was dead. After I jumped it, it would stay running on its own. But if I shut the car off for a while and go to start it again it wont start. So battery not holding charge? Anyway, once it was running I noticed...

Ok, I got the car started up and its staying alive now. Its also now throwing code 24. The car would start up and idle for about 5 seconds then just die, during that 5 seconds if i tap the gas it dies. However, if I punched the gas pedal it would hesitate then rev right up. Also found that...

Shouldn't the car still at least start up and idle even with the AFM unplugged? So if the AFM was bad it should still start up and Idle. Or am I wrong? Cause the car wont stay running, it'll fire up then die.

what should I do to verify if the AFM is bad or not?
