My car was doing that EXACT same thing...i put new plugs and wires...didn't do it...cleaned my MAF and it has been running strong ever since with no problems...i'd suggest tryin that...get a can of MAF sensor cleaner for like 7 bucks at a parts store...you hafta get "tamper-proof" torx bits...25 size maybe? and just clean it real well..if it works but you keep having to clean it...might be time for a new MAF...good luck...
