Well I took the MAF off and cleaned alot of the dirt/dust and yeah you are probably right about the oil. It just dawned on me that I haven't performed a decent tune up in a few thousand miles. Tomorrow I'll be doing this and see what else I can find. The symptoms are: Engine really sounds like it is struggling to get up to 60 and maintain when coming to a hill. Is this characteristic of an engine running lean? How do I cure this? <img src="/forums/images/graemlins/confused.gif" alt="" />
