Friend of mine is having problems getting his car to idle. 89 GTU... It will start and run fine IF you keep the gas pressed down. But it will NOT idle on its own. If you start it without touching the gas it will start fine and rev up to about 3k then die.

So we are thinking either HUGE vac leak which we cant find OR we also heard that if the ECU doesnt match the MAS that it wont run right.

Any suggestions?

 

yea someone tell me WTF is wrong with my car haha. i have 2 ecu's N351 and 2 MAS's one is N370 and other is N350. anyone know which is for what? or w/e?

 

i think the N270 is the TII... cause my s5 tII ecu is n370

 

k yea mine is an n/a so if the 370 is for a t2 then hmm

 

Anyone know?

 

no crap. anyone know? at all? someone?

 

is your AFM connected? The pressure sensor on my S5 NA is N350, so plug that one in and make sure your AFM is plugged in, then start the car.

 

hmm didnt knwo that the pressure sensor has a number code on it or w/e. if its not matched up with the ecu and the MAS will it not work right and cause no idle?

 

the ecu, bac, mas, and pressure sensor are all matched up. still no idle
