, possible solutions include: a.. In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling b.. Inspect all vacuum and PCV hoses, replace if necessary c.. Check for a dirty fuel filter and proper fuel pressure
