'97 cavalier 2.2L Trouble
I have a '97 cavalier 2.2L that runs and starts good, but, under load and lower rpm (1500-2500)it jerks the car with sharp and quick power loss surges along with the odd backfire. Then at high rpm is good acceleration and power. Now with 220000kms, I think after investigating that the timing chain may be worn or stretched. Is this a common problem with these symptoms and mileage? Note that I have replaced spark plugs, air and fuel filter, PCV valve and checked wires. Any info is appreciated. Thank You.
