Engine Performance problem
2000 Mercury Sable 6 cyl Front Wheel Drive Automatic 125000 miles
my sable has the 3.0 dohc engine and for the past two days it drops below 1,000 rpms when at idle and just shuts off sometimes. Do think it is the IAC valve? I put injector cleaner in the tank but still no effect. Thought it could be a clogged injector or something. I dont think it is the fuel pump as the car runs smoothely the rest of the time thru stop and go traffic, on the highway and up and down steep hills.
Question #2: same car has a whining noise on the right side of the engine towards the front that just started about three weeks ago and is there all of the time now when the engine is running. It increase when you step on the accelerator and becomes more pronounce when you turn on the a/c or heater as its putting more strain on the motor. I have replaced the water pump, alternator, power sterring pump and the serpentine belt. Can you please help me?
have the same problem?
