That CEL (check engine light) is just a kid in class waving her hand trying to get you attention because she has the answer. You need to have the codes read. Some places will read them for FREE. Try Autozone or Advanced Auto Parts. Get the exact code (like P0123) not just their translation into English and post it back here.

A dirty fuel filter, or a dirty air filter can cause performance drop off. After putting in a clean fuel filter, put a fuel pressure gauge on it, put in DRIVE, run engine at 1500 rpm for two - three minuets. watch the fuel pressure. If the fuel pressure begins to fall, it could be a defective fuel pressure regulator, or a weak fuel pump.
