Engine Performance problem
2002 Chevy Express V8 Two Wheel Drive Automatic
THIS VAN HAS 190,000 MILES, IT STARTS EASY AND IDLES FINE BUT UPON ANY THING MORE THAN A GRADUALL ACCELERATION BOOGS DOWN AND BACKFIRES UNTILL IT HAS BEEN DRIVE FOR A HALF HR. OR MORE. THEN IT DRIVES OKAY UNTIL IT COOLS DOWN. THE ONLY CODE THAT EVER COMES UP IS P0302. I DID A COMPLETE TUNE UP MINUS WIRES THEY ARE ONLY A YEAR OLD. STILL NO CHANGE.
