hey guys. i have a 2002 Pontiac firebird with the 3800 series II. My question is if anyone knows what could possible be wrong with my car. The other day i noticed if you gave the car gas under a load at 2000 rpm it will stutter and sound like a miss but it is soo rapid and no backfire so it is drawing me away from the miss theory. I checked my timing and when under the load the timing is off 10 degrees. I changed the spark plugs in October with ac delco iridiums and have brand new wires i just put on yesterday but still nothing. When i checked the voltage from the wires while break torquing to get the car to studder the voltage became very high. I have no codes or anything and i scanned the comp to find nothing at all. Before i spend any more money i was wondering if anyone could help. I guess it could be a bad knock sensor or a bad egr valve, ecm computer, or bad ignition coils. PLEASE HELP!!! THANK YOU!!!
