Alright i finally got my car up and running thanks to all the help of everyone but i need help once again!! :dunno:
Every time the engine starts it seems to lose air and
it losses power and ends up dieing.
could it be the rpms??
how many rpms should i keep the car at??
I really dont know alot about these cars all i need are some pointers
thanks to anyone that helps!!!!!

vacuum lines are good

 

[the supra kid91]

check for loose connections

could have dirty throttle body

check your MAF, i took off my MAF to check my turbo shaft play and tryed to start it and the would die instantly.

 

[Slow_Sc3]

check for loose connections

:werd:

any leak after the afm will cause the car to act funky

 

[87supraboost]

all vacuum lines are good.
i took the throttle body off as well along with the sensors and cleaned them and they all work
my MAF looks great and works

change your injctors seals/
hey just unplug everything that plug in and clean them.

what rpms should the car be kept at normally??

 

[7mgte is a pos]

you mean idle at?
7mgte = 700rpm
7mge = 650rpm i think

 

[87supraboost]

my supra idles at 500rpm
could that have any effect on it??

The stock idle is 650 rpm. As stated check your AFM electronics box, but also look at the TPS, and the IAC. All of these effect your idle speed. If you can possibly swap afm electronic's, that would be a good start, because it usually is the culprit. Just remove the little screws that mount it to the AFM housing, disconnect the harness, and gently pull the electronics box straight out. ( It has a long sensor that goes down into the housing). I got a replacement at the local junkyard for 35 bucks. I still have it if you can't find one.

He nipped it in the bud. I'd check and clean the IAC first though. I sent you a PM.
