It took a bit longer for our schedules to permit the time for me to check it out, but I was able to glance her over & I did locate several rotted / weathered vacuum lines as well as another vacuum line that had several attempts to patch previous leaks. After replacing the vacuum lines with new ones, I cleared the P0171 code and test drove it, all was good. The check engine light has come on here and there, but seems to stay off for the most part. I did check the code and it was a P0171 that caused it to come on. It has managed to stay off for a while now, so before any further diagnoses could be done, it has had another problem. I will start a new thread describing the latest problem witch all began with a blown radiator hose......
