I think I'm ready to dive in. Replacing the air mass sensor is a fast and easy job. I'll take your word on that. But before I put out the $250 for the part, could you describe briefly what's involved, where is the part I'm looking for, and anything else that I may need to know? Adjustments, etc. I'm not a total idiot mechanically but it doesn't take long in these newer engines for me to feel like one. Thank you for your patience and your help. Bob H
