Could be the Air Flow Sensor - that controls the amount of air going to the engine - the flap that the sensor controls is holding back the air I think.... thats why it runs good cold as a cold engine needs less air and more fuel but as car heats up it needs more air- it seems to be starving for air....???

A practical alternative to replacing parts at random would be to take your vehicle in for a comprehensive diagnosis to identify the real cause of the problem(s).

89 cutlass cierra crank but wont start when wet out unless gas pedal is pushed


This should be a drive by wire vehicle meaning it has a cable for the throttle body. First thing would be to see if any error codes can be pulled up (most parts stores will do that for free.) Drive by wire versus the late model that use electronic control for the idle have a IAC or idle air control which when first started controls the idle air intake--all air is run by it to idle the vehicle when cold--

Usual symptoms are rather high idle when cold engine or even idle and RPM jumping up and down and stalling when cold.

Another way if idle does drop when cold is tapping the gas--engine will still run until hot. Means not usually a fuel pump issue.

You could also have if the vehicle is fuel injected a dirty Mass air flow sensor, a throttle position sensor, etc.

These can be if the vehicle has them cleaned using a special zero residue spray cleaner.

First have it scanned to see what if any errors it shows--the computer.

The engine stops after 2 or more hours of operation


Hi and welcome to FixYa!
Two things that can result the vehicle to stall. A faulty fuel pump and a faulty coil pack. If the fuel pump is faulty it tends to have fuel supply irregularities, one good reason why the vehicle stalls. A faulty coil pack can make the vehicle stall too, it tends not to give current to the plugs and will surely require replacement to resolve the problem.

Hope this helps and thank you for using FixYa! Have a good one!

Guessing gets expensive. Is the check engine lamp ON? If so, there will be stored trouble codes that are necessary to propely determine the cause of the stall. Catalytic converters do not unplug when cold, if they are plugged, they are plugged at all temps and vehicle runs worse the more gas you give it but may idle OK. Typically, stalls after warm are electrical failures, often computers, or solid state components that fail when they heat, and cool off over tyme. Ignition components are highly suspect generally, as are sensors. crankshaft position sensor especially is common to fail only warm on most vehicles.

Engine runs for about 10-20min and stalls. will


possible ignition coil pack breaking down when hot....cools off and works again. pull plug wire off plug and check for spark when in this no start condition.vehicle must have air, fuel and spark to run.
