Hello...
I have an 01 Camry. The check engine light has come on. It has been on for about 2 weeks. The car has been running great, but until today I can feel some hesitation as I am driving down the road, like it isn't getting enough gas, or bad gas. I am going to have it decoded today. Can by some chance a bad fuel filter make the CEL come on? I am thinking it is the O2 sensor since that is the most common thing for the CEL to come on, and I have noticed that my gas mileage has dropped.
Any suggestions? Thanks
