Bucks in gears 3, 4, 5 under heavy acceleration. Have replaced plugs, wires. Recent new CPS and belts. Dealer blames bad MAP sensor. Did not have part in stock. Where is this located on engine? Dealer also blamed K&N air clearner for fouling MAF sensor. Is this possible?

Yes that is possible! Cant beat a good OE style air filter. Just change it as needed. Cant argue with dealer on the MAF sensor. Do you know what the codes were?
