It's been a while since I've needed the support form you guys, my 03 R53 just hit 150K and has been running strong. This past summer I got a p2096 lean code, could not find anything wrong, car was still strong. I finally pressurized my exhaust with a compressor and soapy water found bubbles at the pre-cat. I ordered a scorpion exhaust from Bavarian auto...took 3 months to arrive from England. Installed it (sounds nice with my jcw cat back. But it did not fix my long term fuel trim problems, even after 1000 miles. Replaced rear o2, ic boots (I'm pushing 15psi with my craven 15% pulley; installed after I got code while I had things apart, tensioner, idler, ATI harmonic balancer (awesome btw)Etc. etc. car went in for power steering recall, told them not to touch anything else, a week later limp mode from failed wiring harness at throttle body...earlier replaced throttle pedal for potentiometer code. Replaced throttle body to2 voltages look good, map readings are within tolerance. Sprayed all hoses with carb cleaner , starting fluid...no evidence of vacuum leak. Long term fuel trim at 11%, bought gt1/DIS but can't get it running on 64 bit machines. :mad2: Anyone on northern NJ that can clear my adaptations?
