I installed a JL Diablo chip on my '01 L and ever since, it seems to have a stumble at idle. If I sit at a light for a while, I will feel a stumble as if the idle RPM has gone down, but the tach doesn't move. It only happens at idle and was just wondering if anyone else who uses JL's chip has had this problem and if its normal. Thanks.

 

Try pulling the chip and re-cleaning the termials. Sounds like you may not ahve a solid connection.

 

As with 98% of most chip problems, check your connection, and go from there. Most people DO NOT clean the contacts enough the first time out. hope this helps

 

Great minds think alike

 

Great answers, what they said.....If that still doesn't work, Call or E-Mail JL....
