Hello Tsikoteers,

Does anyone here ever encountered an idling problem usually around 1200 to 1400 rpm range while at the same time the check engine indicator illuminates. Is this related to a dirty fuel line/fuel filter,injectors or it has something to do with my cars timing belt/tensioner. My car btw is a lancer 97 model (pizza pie) already at 185,000 km reading. I've already had my oil change, sparkplugs and even added a cyclo "fuel/injector cleaner" so to clean the fuel line and injectors but still the same problem. My last timing belt/tensioner change was when the car was at 85,000 km. What might be the problem here for I never encountered such probem before. Hoping for your advice.

Thanks and more power.
