What do I do about the warning light on my Corolla?
Hi, I have a 2004 Toyota Corolla and the engine management light keeps coming on and then going off after a few days. It could be a week or more before it comes on again. I brought it to a mechanic and he said that it was a problem with the oil pressure release valve and he flushed out the system and replaced the oil, but the light still came on. He said that he was onto Toyota and it said it was not a major problem. What do you think?
