My 2000 Toyota Celica GT has a check engine light on it. I took it to an auto parts store and had it scanned. It gave me the following codes:
P0300 - Random Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0171 - System Too Lean (Bank 1)
I put fuel injector cleaner in it today, as well as cleaned the MAF sensor. Sometimes when I'm accelerating, the check engine light flashes then goes back to staying on. I've checked all over for vacuum leaks and cannot find a thing. I've noticed a little oil on top of the engine, but I'm not sure if this is related to the the problem.
