strange problems

DaveSakky135 · 09-02-2012, 04:46 PM

Been having some strange problems with my 1er. After installing jb4 on map 1 and 5 i have been getting some strange stuttering in high rmp's. Not having changed plugs i ordered some and am guessing that will solve the problem.

However today i was driving on map 1, and under normal driving conditions my limp mode light came on, the "brake" light lit up in yellow, and when i pulled over the rpm's were jumping up and down at around 1,000 rmps.

I have no codes as the jb4 erased them, however after restarting the car it ran fine.

Any idea what is going on?

My car is an 08' and has 90,000 miles on, but has only been tuned for the last 10,000

thanks,
David

Sounds like you had some misfires. I would change the plugs and see if the problem persists. Also turn off the autoclear so you can read the codes if it happens again.

Hard wire or PnP? Maybe something is loose? Codes?
