I have a problem...I've had this problem actually ever since I bought my RL. It involves a sort of "missfire" and a stutter when I accellerate. This morning, I had to slow down a bit due to a car turning on a highway. When I tried to accellerate back up to about 60 mph from around 40 mph, my car started to stutter, and wouldn't budge from 40! Then (as other cars are speeding around me to pass), my TCS and Check Engine lights came on. What is the problem!?!! I've had my coil packs switched around, and spark plugs replaced in the past, and both have been temporary fixes. I just don't seem to understand why this keeps re-occurring. I'm thinking fuel injector issues? Any suggestions? Help! I really don't wanna hafta take it to the dealer again....
