Code: 29D1

[hbwav2002]

This is a misfire code.

I am only getting this when my JB4 is on, i can't replicate it on map 0 or when the JB4 is out.

My question is this safe to keep in my car when i go to the dealer or should i delete it?

I have been meaning to go to the dealer because whenever i accelerate hard with my JB4 i get this code and i go into limp mode.

I have searched a lot on this in the forums and have seen similar problems with other people, but i haven't been able to figure out what i should do.

Any help would be very appreciated.

Thanks.

What are your mods? Mileage? Could be any number of things from injectors to plugs and coil packs even carbon build up on the valves. If your still under warranty remove the JB and take it in.

I'm stock except for my jb4, and I only run map 1. I'm at 44,000 thousand miles.

I'm definitely going to take the jb4 out before I go to the dealer. But im not sure if I should keep or delete the code that is showing up before I go in.

If it's the only code keep it. They wont troubleshoot it without a code. There's another code for the "tuner" code I cant remember what it is, but it says manipulation something.
