I had this problem with my 2001 Jimmy 4.3 - It turned out to be a leaky intake manifold gasket. Mine would stall after it warmed up and wouldn't restart until it cooled down. Other issues I've had we're fuel pump related. You might want to start there.

1993 Ford Probe GT it will start but then after 5-10 minutes the engine warms up and it turns off What might be the problem?

A common problem on various ford models is distrbuter module cutout when the car warms up. This will kill the engine and it will not fire until the car cools. The module is the chip attached directly beneath the distrubuter. Replace the module and this stands a good chance of fixing the problem :)

Why does your power steering work perfect when you start your car and its cold the second it warms up you have no power steering anymore?

Could be that your low on power steering fluid. When it's cold, the fluid is more viscus, but once it warms up and thins out there isn't enough.

What would cause a 190 Nissan Maxima V6 to run extremely rich after warming up Starts fine with a cold engine Once it warms up you can smell unburnt fuel and it will not restart for at least 15 minute?

Checl your manual for a cold start injector. if it has one check your voltage after it warms up. if you have voltage after car warms up you have a problem with the circuit. if you don't have voltage, remove and plug the fuel line to this solinoid, start and run car and check your symptoms again.


Your 1992 Oldsmobile 98 runs then shut off?

Check your cam shaft sensor or your crank sensor, if it starts from a cold start and stalls when it warms up that might be your problem... Took me 2 months to find that out ..
