It's a series 4 and previous owner set it up but having problems with car ...Had a few bad injectors and after I changed them car idled little high so I reset base idle and now car has slight surge when cold start and when in drive..otherwise runs ok...Not sure if car was tuned with bad injectors or not..what a pain trying to figure out things other people have done without knowing. ...thanks
If you don't have one I'd suggest getting a Wideband. And if your not 100% sure how it was setup, then taking it to a tuner would definitely be your best bet. That's the tough part of buying a used car that's been tuned already.
