It just puttered out and stalled - and would not start. I towed it in, cleaned out the airfilter, cleaned the connectors on the MAS and the MAP and suddenly, she ran again - for a while that is... then it sat for a couple of weeks now it wont start again. How do I diagnose where the problen is coming from? REALLY APPRECIATE anytimely and engaging feedback because it is in a place where I am likely to get towed. Thank you in advance... Please ask me any additional questions to help me draw the correct conclusion.

 

Have you checked for fault codes using the on-board diagnostics?
