Hey guys!
Having some trouble with my GP and have run out of options and ideas as to where to look. Some background on the car.....bought it in july of '11 and so far it has been a good solid car(came over from an Audi) but recently have begun to give me problems. It would die on me in the middle of driving even approching 80 mph would shut off and after a minute or two would start right back up. I had concluded that the Crank Position Sensor had gone bad. Which brings me here. I will be honest, I followed the DIY found on the forum and all went well pretty easy job. Now at first I didnt hold the flywheel as I tried to break the harmonic balancer bolt loose, and i dont know if I threw something off....but eventually threw some vice grips on the flywheel and proceded as the DIY stated. Within 24 hours of changing the CKP sensor I began having BIG problems. I had idled the car for about 45 mins while detailing the inside and when I finished went to fill her up and placed it into drive and as i pressed the gas noticed the motor chugging and making a hissing sound like opening a 2 liter bottle over and over coming from behind the firewall on the driver side.
As I drove to the gas station i noticed that as i approch 2000 RPMs the motor chugs and makes the hissing and doesnt want to accelerate. I also noticed that the boost guage on my DIC is boosting as if it is at half throttle under heavy acceleration. Had it run for codes and came back with P0102 MAF low, P0122 TPS circuit low, P0171 Bank 1 lean, P0300 Random Misfire, P0336 CPK Sensor 18/24x out of range,P1122 TPS circuit intermittent low, P1571 PWM circuit no freq./signal. Erased the codes and P0122,P1122, and P1571 came back. I have change out plugs and wires removed and cleaned the MAF, Replaced the TPS, Cleaned the Throttle Body and IAC Valve also replaced the Throttle body gasket. And to no avail i am still having the same problems as if nothing I have done has changed anything.
I have exhausted the search bar and come up with most of the information leading me to the work already done and I am unsure on what to do next. I know that there is a ton of experiance on here and I would really appreciate any feedback. I want my car back on the road and really want to get her running the way she was. Please Help!!!!!!
Thanks.
