engine light comes on while going at an uphill pull and loses power
I have a 2002 Chevy Silverado 1500 pick up and the engine light comes on while driving uphill and loses power , have changed senors and wiring and spark plugs, any solutions on what else could be wrong. Stumped
The check engine light only comes on while going up hills? This could be any number of things. Either a sensor or component is failing only under those conditions or something else is effecting the PCM like a slightly plugged exhaust, bad injectors, etc. For issues like this it is cheaper to get a scanner that can read you PCM codes and live data during the issue then you have an idea where to start.
