lst gen b16a,j1 tranny,pw0 in my lil rexy..

Ok heres the problem..now..I'm able to start the motor
will no problems at all.
as soon as it gets to operating temp..the engine
stalls..throws no codes what
so ever...air fuel guage indicating that i'm running
sufficient fuel..even my fuel
pressure guage is a all go too @ 40 psi...so definetly
can't be a fuel thing.

I just replaced my coil and cap..since it was charred
when this situation occured..
which i though would solve the problem..but still a no
go situation..I also checked
spark by grounding a spark plug wire to a ground
chassis. Turns out i got spark

I have checked all connections,possible fuel leaks all
the way up to the injectors,
other distributor components, still puzzled.......
no codes, no damn clues..

engine just shuts down as soon as it gets warmed up...


I would definetly appreciate the feed back guys cuz my
*** is
stuck like chuck...TIA

Does it stall at all rpm speeds? I mean, if you hold the throttle will it stall? If not, then have you tried just adjusting the engine idle speed? It might be set too low, y'know. Simple solutions are always best .

Anyway, what else was I going to say... oh yeah. It's got to be a problem with the ECU operation mode. That means a problem with one or more of the sensors used when the ECU is in warmed-up operating temperature (I forget if it's called open or closed-loop... I think it's open-loop). Otherwise, it would be exhibiting the problem ALL the time, warm or cold. So for that reason I doubt it's a problem w/spark or fuel or ***** like that.

It's probably not a vacuum leak, since that'll cause a funny idle, but not stalling. It might be a MAP sensor problem.
