    You'll need to have the codes pulled from the computer. It could be a couple of things, check the connections at the coolant temperature sensor and the intake air temperature sensor

Sounds like it is most likely a sensor in your intake system, either mass airflow, air temperature, or map sensor. Autozone and Advance both pull the codes on your truck for free. I have a 93 Eclipse that did the same thing with a hole in the intake tube, so check that too. Hope this helps :)

Engine stalls


Hi, car stalling problem often means the engine is not getting enough fuel and/or too much air. A cold engine needs a fairly rich fuel mixture to start, and to idle smoothly while it warms up. Any of the following could cause or contribute to this kind of stalling problem which i would not want to exaggerate until i get a clear picture of how the car stalls.

Does your engine stalls when you stop for a traffic light or when idling, or your engine just stalls unexpectedly while driving?
Answering the question will help me determine the cause of the problem.

Car can stall in warm weather


Most likely if it is temperature related you may have a temperature sensor that is failing. The sensor may not be reacting properly to the actual temperature and causing the engine to run rich in warmer weather when a richer setting is not required.
You could have a sticking injector or sticking EGR valve or a faulty TPS switch, all can cause a rich condition and a poor running engine.
Is the service engine light on or come on at some point?
I would start by having the car scanned for trouble codes. You can have the scanned at no cost to you at your local Auto Zone or Advance Auto Parts. Write the codes down and respond back.

1997 gmc k1500 runs really rich


Hi there,first of all you must synch the cam/crank sensors. To do this put the engine on top dead center remove the distributor cap and look very closely at the dist housing there will be a 6 mark and an 8 mark loosen distributor and rotate untill the rotor points directly at the 8. The marks are small so get a light and look closely.Clear codes and restart. Is vehicle still running rich?

Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.
