Hi,
I have a new 2005 TJ Sport with a 4.0 / 6 speed manual. Driving around town on drive roads the engine has a slight lag in response, most noticable going into second and third. The lag / hesitation is less than a half second, is not accompanied by any miss fire and no error codes are posted. It starts fine, runs at high speed fine, and exhibits no other problems. Driving my
2000 TJ (identical except it is a 5 speed and mileage) is markedly different (same dry pavement, same gas). It's going back to the dealership on Friday (under warranty)Anyone have a similar experience? I'm leaning to the ECM and the fuel map. Thoughts? Thanks, Michael
