Hello ladies and gents. I just picked up a 95 Talon TSI AWD. The car is running really rich. Enough so that the car blows black smoke while driving. Running a datalog on the car with my OBD2 tool shows both front and rear O2 sensors are flat lined at .1v at all times (idle, cruise, wot). When letting off the throttle to slow down the front O2 will raise to .4v for a few seconds and then drop straight back down. All fuel trims are pegged at 12% and 24%. Also when driving, when I push in the clutch from under any boost pressure at all the car will overload with fuel and stall out. I checked the resistance of the front O2 sensor and reads 23ohms. Checked the wiring to make sure the cruise control and front O2 plugs were not reversed. Checked wiring to make sure it is seeing voltage also and I get battery voltage at the connector. This weekend I will be doing a boost leak test and a rear O2 simulator.
The car is all stock except for 100mm crank, eagle rods, wiseco 9:1 pistons, intercooler, and 3in turbo back exhaust. The BOV is still recirculating and working correctly. I have searched the forums and done multiple checks on the car and nothing yet. Any help would be appreciated.
