Question about 2006 Volkswagen Passat
It is not a fuel issue. Before these problems I changed the fuel regulator and the fuel pump and fuel filter are both new recently changed. It has new plugs, cap and rotor. I changed a faulty temperature sensor, the one with 4 prongs. Before this problem it started idling rough like it was overfueling and one cylinder wasn't firing. It isn't an injector problem and is definitely a sensor or otherwise electrical. It seemed to be loading up on fuel during idle and stalling. This progressed to the 5 second run and stall. It was leaving lots of carbon on the ground from the exhaust. Since I changed the heat sensor and fuel regulator the 5 second run time is smooth. When I start it it will do one of two things. It will run for about 5 seconds and then stall or it will run for a quarter mile then stalls. Once it does stalIs it will only run for 5 seconds. If I leave it sit it might run for another quarter mile and get me back to my yard. I tried disconnecting the battery for 20 minutes to see if the problem could be a reset issue.
