Todays Engines require maitainance, Filters, Polution controls, Tune Ups ect.If your Check Engine Light is not on it's not that serious.Some things to try to inprove start and idle, add a injector cleaner to a full tank of gas, it will take a while to improve but if it's dirty injectors it can help.I don't know the milage but at nearly 5 years you could need a Tune Up $ 150-250.Good Luck.

Idle fluctuates on 1995 f250, sometimes dies, sometimes revs, no apparent vaccum issues, IAC with scan tool reads low voltage issue. Could this be vaccum, charging system, faulty computer? Problem is...


Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

Why does my engine keeps shutting down and sometimes have an irregular or fluctuating rpm reading?


If this happen only when the car is at idle it's your idle air control valve if it happens while your on the gas then it's your throtle position sensor.
