2002 Silverado. When it become cold ( below 30) the truck seems to not want to idle. While driving the truck runs fine but when im at a stop light it stutters or acts like it wants to keep going. Today it actually shut off after doing this a couple times. It started right up. Any suggestions on what to look at?

SOURCE: 99 chevy silverado Unstable idle when it worms up

Hello;
It sounds as if you have a small vacuum leak some where in the intake system. Also since you cleaned the throttle body also clean the MAS. It is located between the air filter housing and the throttle body. Hope this helps, rate me highly.
Thanks;

SOURCE: O2 sensor problem, running rich. Please help

was the code for rich or lean? may try cleaning mass air flow sensor. it is in the air intake tube and has a flat wire connector. take out of tube and take four torx bolts out and clean with mass air flow cleaner or brake cleaner and put back in when dry. or it could be a bad wire on the o2 harness. look for chaffing or broken wires in harness by o2. also could be the exhaust system has a slight blockage. could also be some other things but try these first.

SOURCE: Chugs, acts like it's not getting gas once warmed up. Idle's fine

This problem can be several things. When your engine is cold, your computer is in a "closed loop" and just pretty much keeps the engine running until warmed up. After reaching operation temperature, the computer starts reading all the sensors. If one sensor is not connected or is defective, you will experience performance problems. Most of the time this will turn on the check engine light, but not always. Second is the fuel pump. This too will cause erratic engine problems.

SOURCE: idel problem on 5.7 1995 silverado

You engine is TBI, It uses a MAP sensor check the vacuum line for crack and make sure yo have a good seal, The distributor also check and make sure the pick up does not have corrosion which causes the relutor to stick. As for the EGR it would cause a misfire, and yes the do fail. I am sticking with the IAC as a problem its a stepper motor and has a high failure rate, chack also the ECT (engine coolant temp sensor) for corrosion that gives false reading.

Engine running to cool


Replace the thermostat. If thermo is stuck open, coolant only heats up when there is no flow over radiator(idle) and then cools down when driving. Also, check coolant level, same response as stuck thermo.
