1999 BMW 323 Acceleration
Engine Performance problem
1999 BMW 323 Manual 91,000 miles
I am having acceleration issues. For example when I am on the highway and I go to pass someone my car is not accelerating properly. It is hesitating before it will engage and give the boost of power needed to pass the car. I have recently replaced the oxygen sensor, intake boot and air filter. I am getting ready to replace the camshaft sensor and the fuel filter. Do you have any suggestions on what may be causing this issue?
