RS16017 Posted May 22, 2017 Report Share Posted May 22, 2017 Picked up a Shelby the other day. Has a bad miss in it. Has a JLT intake on it. Don't think it was tuned after install. The air to fuel ration stays pegged at 20 sitting at idle. What would be the solution to this. Quote Link to comment Share on other sites More sharing options...
mhr1961 Posted May 22, 2017 Report Share Posted May 22, 2017 You may want to check your coil packs. Quote Link to comment Share on other sites More sharing options...
Secondo Posted May 22, 2017 Report Share Posted May 22, 2017 Congrats! Sounds like they took the CAI tune out of it and put the original factory tune back in. Did they give you the original stock intake? Put it back on the motor or get a performance tune. Quote Link to comment Share on other sites More sharing options...
