I HAVE A BIT OF A PROBLEM. I HAVE CHANGED ALL SPARK PLUGS AND WIRES AND NEW DISTRIBUTER + CAP. THE PROBLEM I'M HAVING IS NOW IT SAYS #4 MISFIRE I RESET IT 3 TIMES WITH MY CODE READER, AND NOW THE TRUCK WILL NOT START RIGHT AND WHEN I PUT IT IN DRIVE IT SPITS AND SPUDDERS.
I CHANGED THE COIL OUT WITH NEW THAT DID'NT HELP. WHAT ELES CAN BE WRONG OR SHOULD I JUST BRING IT TO THE DEALER.

If you did not have the code before the tune up, Recheck the spark plug and wire on the misfiring cyl
if the tune up was done to correct the same code
should do a compression check and check injector
good luck
