I have a 04 TJ Sport - 6 cyl. The RPM's are slow to reduce especially when the engine is cold when I push the clutch pedal while shifting between 1st and 2nd and again between 2nd and third. I've cleaned the throttle body and AIC motor. My next step is to check for vacuum leaks but I thought I'd check with others to see if there is something more likely causing the problem.
Any suggestions are appreciated.
