yes, MAF is mass airflow filter/sensor. I had the same problem and i just cleaned it with some brake cleaner and it improved a bit. Also take your Idle Adjusting Valve off and clean it with carb cleaner, you will have a lot of crap coming out, mine did. Also throttle response improved quite a bit after those procedures.King Daffee wrote:Thanks for the suggestiongsI am pretty sure that it is closing all the way MAF is mass airflow filter i am guessing?
