About a month ago, I had a tune up done on my car, where the spark plugs were replaced and air filter changed. After that the car ran as good as it ever has. It was quicker and when you stepped on the gas it went immediately. Now this slight hesitation is coming back, where whenever you step on the gas it will take a full second to accelerate. Does anyone have any idea what is going on?
Car history: 2003 6s. Transmission replaced in '06. Various o2 and knock sensor issues in '06 & '07. Throttle positioning sensor replaced last October, to correct a MAJOR hesitation issue.
