how do you test or check the crankshaft position sensor and mass air flow sensor
(1) Answer
most techs will use a scope to watch the patterns. a shop can do this for you for a nominal fee. that will pinpoint your failure, if they are suspected.
did you check the basics first, like plugs, wires and coils??
