I have a 89 s5 with a jspec engine. my problems is that my car cranks over and sometimes is starts most of the time it doesnt. but when it does it smokes a bunch it smell like gas il would idle for about 30 secs and then i dies and when i try to crank it over again it does not even start. i check to see if it has any vac leak, by spraying it with carb cleaner and i dont get any change in rpms. when i get the car to idle and i tap the gas it either dies or rpms go hell of low like 100 rpm. im thinking that the ECT is not reading right and is sending the car into close loop at start up and it runs it very rich likes its doing. or a Very slow and lazy o2. any ideas you guys??????

 

Tps

 

it oculd be tps or maf, my 240 did the same thing when my MAF went bad. Try unplugging the maf and see if it keeps stalling out, if it doesnt do it then you have a bad maf.

 

whats strange to me is that the car was runnig hell of **** before my wire harness were fried. my tps, and my maf sesor were all in good spec cond. i saw a post about fuel psi but i just got a walbro 255 and it was runnig very good. i gess i have to checkl fuel psi

 

if you unplug your MAF, it will run like horrible ****, if it even runs at all

although it could be the MAF

i dont know much about walbro, but jetting could be the issue

 

i just think i found a couple of prolblems that might be it for one the BAC valve conection was broken and my alternator was fucked up, and my injectors were plugged in incorrectly (all that Sour D) but im putting everything back as we speak or type. i hope this is it man cuz i wana go drving and hear thoese two rotor symphonie controled by that turbo conductor

 

good luck
