a believe you mean maf sensor? clear codes after plugging it in and you should be may take some time to reset fuel trim though but it will on its own
Yes I did mean the MAF sensor. I disconnected battery and reconnected but still will not start. How do you clear codes?
need a scanner and see if other codes are there also
