2002 Ford Escort ES System Lean Code Engine Light Problem?
Reader Question
My question is about a check engine light. I got the code pulled and its saying the system is too lean, I have a 2002 Ford Escort ES edition. Its not a oxygen sensor because the last mechanic I brought it too replaced that and its still on. Can you help?
Sincerely,
Mike
Hey there Mike
That code is pretty vague and could mean many things, but I would first start by replacing the spark plugs, plug wires, clean the throttle body and idle speed control motor….basically a little tune up.

Thanks Austin I will try getting that done. When the code was pulled it said system too lean bank 1 if that helps but I do appreciate the time thanks!!
Hello again Mike
Yes, I would proceed with a tune up and would also look at cleaning the fuel injectors.
