1990 Bronco stalling out

I have a 1990 Bronco and am having some trouble finding what is causing it to stall out after it has been running for about 15 to 20 mins. I have tried cleaning out the throttle body changing the ignition moduel , removed and cleaned out the idle air control valve flushing out the injectorschanging the fuel filter. It only happens when I come to a stop and it will start right back up after but I have to two foot it to keep it running untill I let it cool down for a couple of hours. any suggestions?

Re: 1990 Bronco stalling out

Sounds to me like it is low on coolant, especialy since you say the throttle body is clean and the IACV is good.

Re: 1990 Bronco stalling out

I don't really understand how if the coolant is low it could cause the truck to stall out?
I checked the coolant level and it was full , I wasnt sure if maby even though I cleaned out the IAC it could still be sticking?
The ignition moduel has been replaced , the fuel filter, MAP sensor, plugs, wires cap and rotor are new. any other suggestions?

Re: 1990 Bronco stalling out

How about the coil? Sounds like a heat transfer problem. The only other thing I can think of is to check fuel pressure.

I'd check the ignition module... I'd also check for trouble codes!

Re: 1990 Bronco stalling out

I have seen many people replace the pickup for no reason! Yet to see sombody replace one that actually needed replaced. I'd take the module off and take it to autozone or advance or orielly and have them test it.. Very well could be the problem. Also check for trouble codes! they can tell you alot if you have a problem and its free to do so.

Re: 1990 Bronco stalling out

check your EGR valve might be sticking open, esp if your coming to stop from above 40 mph. disconect the vac line to egr also ckeck the egr solinoid filter, little sponge under plastic cap on top of soliniod.
Hopes this helps Good Luck
