86 5kt dying...help!

[Lawrence C Leung]

Sounds like a vacuum leak or Intercooler leak. Check all hoses, or do the
stall test, per SJM (pull dipstick when car is in park, at idle. If leaks
are minimal, or stopped, car should stall when the stick is pulled due to
the massive vacuum leak of unmetered air. If it doesn't stall, keep
searching hoses). Check your intercooler (largish black radiator like
device right in front of the engine) for leaks. If there is oil on the
underside of the intercooler, it's leaking. Check archives on how to
repair. Finally, check the Michelin man hose OFF of the CAR. Its the 
ribbed hose between the intercooler and the engine. REALLY poke and prod
at it! Also, if you hands are big enough, cover both ends of the hose
with your palms to seal it, and compress like an accordian. It should not
leak.
