This doesn't make sense. You need to start a new question, and PLEASE list the engine size and mileage. This post is many years old and was a private conversation between the people involved. No other experts are going to see it or have a chance to reply. That does you a disservice. When you write your question, be sure to include specific symptoms, and everything you've tested so far, and the results. If there were diagnostic fault codes, we need to know those code numbers so we can get an idea of where to start.
