Engine Performance problem
2002 Jeep Cherokee V8 All Wheel Drive Automatic 62,000 miles
Hi guys. My Jeep Grand Cherokee Limited is in excellent condition and had the 60K mile service done several months ago. It runs very, very well.
However, the last couple of times starting the car has been concering, as the idle is very high/rough with the start-up, but it drives normally. I also notice it's reving high while in Park.
In retrospect, I added a few gas tablets to the tank when I last put gas in, but I forgot to fill up completely. I filled the gas tank about 1/2 way.
Would too many gas additive/tablets combined with 1/2 filled tank cause this high idling? If so, can I just " drive it out"? Or is this coincidence and should I be concerned that something else is wrong?
