Re: engine light started blinking when going up hills, now it is always on
Hey there, the guy who did the compression test was at a GM dealer and he said that there was just no compression in 1 and 6. He did not have the results which is a bit fishy but he was adamant that the cylinders were dead. He did not pull anything to check so I am still holding out hope that it is not too major of a problem.
If 2 cylinders were gone I dont think that it would even be able to run. It runs fine after about 20 mph, cant even tell there is anything wrong except that the light blinks. Could it be that one of the sensors could be faulty? I am taking to a friend that I trust just so he could "really" take a look and see what may be wrong. I'll mention the timing thing though.
The truck runs fine except for when it is idling.
