Sometimes happens more in cooler weather while driving truck stops and says reduce engine control check engine light reads sensor can i change just the sensor or what is the cheapest fix I can do
Power steering fluid low and leaking around master cylinder.
running rough,stalling,engine dies when press gas pedal.
I have heard that a map sensor could be bad,when you start it files rough. I have heard that the air compressor could be bad but I think I hear come on
WHEN I CHECK WITH ONSTAR DIAGNOSTICS THEY SAY IT IS NO LONGER A PROBLEM BUT HAVE IT CHECKED IF LIGHT STAYS ON. IT IS NOW ON FOR OVER 10 RESTARTS. BEFORE IT WOULD GO OFF AFTER 4 OR 5 RESTARTS. SHOULD I BE CONCERNED?
When you start it up you can hear the air pump start,but it says according to the program guide that comes up.
Can I get replacement light sockets for the running lights?
havent found a place on the southside or chicago that specialize in just tune ups
Hi , I need some help. after I change battery RPM is too low and engine is stall when I press brake pedal near traffic lights and roundabout
i also get code P2135. this causes enginge to pretty much shut down and if something like damaged floor matts causes this, then that is very discomforting and dissapointing for GM. What the hell??
It's intermittent. All of the gauges just go off, then for no apparent reason, come back on. Nothing works, speedometer, fuel, oil pressure, etc.
