OK, I hope someone here can help me. I've got a series 5 J-spec 13BT with great compression. However, I can't get the DAMN thing to stay running. I've got all the stock turbo electronic goodies and they ARE plugged in right. I just don't have the knock sensor or the O2 sensor plugged in. I also have a leaky secondary. No vaccum leaks.

the mods I've done:
FCD
ACV and air pump removed
throttle body mod

Engine symptoms:
Starts easily and idles up high/smooth,like AWS(which I don't have anymore) is kicking in. White smoke puffs out of exhaust. Then engine just dies. Like fuel cut or engine lost spark.

HELP HELP HELP

 

Check the whole intake from Air Flow Meter to the turbo for air leaks or cracks. My car did the same yesterday and when I checked under the hood the intake had come loose from the turbo's intake... Also make sure that the TPS is plugged.

I got a home made TII, it is an 87 GXL 6 port engine with ported exhaust, 91 TII intake manifold (ported for the extra ports), 91 turbo and exhaust manifold, factory intercooler, TII Throtle cable, N/A ecu and harness, No air pump, no air temp sensor, no acv, no oxigen sensor, 12A Turbo secondaries, 3" single exhaust, silencer, Ultra Flow Chrome Round muffler, automatic tranny, a/c and runs great (Still breaking in)...

 

Yeah, I'll check that. **** my AFM isn't even connected to the intake right now. Just plugged into the harness. HOPEFULLY, that's the culprit.Thanks

 

HEY thanks for the advice. That was IT!! engine started up great!! thanks agian

 

Glad I could help...
