Engine Performance problem
2003 Chevy Monte Carlo 6 cyl Front Wheel Drive Automatic 92000 miles
My Monte Carlo has a hesitation in the acceleration at higher rpm's. When you try to accelerate, it is sluggish. It will accelerate fine at lower rpm's, but once you step on it, there's nothing. It hesitates and sometimes eventually speeds up. Most of the time, either one of two things happen: either the car doesn't respond, or the rpm's jump up with no actual acceleration. I had the cruise control on today and when it tried to speed up to maintain the speed, the rpm's jumped up and a whining noise came from under the hood. I have replaced the fuel filter, plugs and wires, pcv valve, and used injector cleaner. Any suggestions would be greatly appreciated.
have the same problem?
