GMC Repair: ENGINE MISSED BAD AFTER WARM UP, pontiac grand prix, pontiac

Question
I HAVE A 1995 PONTIAC GRAND PRIX THAT HAS A LIGHT MISS WHEN COLD BUT AFTER IT HEATS UP TO NORMAL OPERATING TEMPERATURES IT GET MUCH WORSE. I'VE CHANGES THE PLUGS, WIRES, FILTERS ECT... BUT IT STILL HAS THE MISS..NO ARCHING ANYWHERE..NO TROUBLE CODES SET. ANY HELP WOULD BE GREATLY APPRECIATED. THANKS.

Answer

What engine size ?. Does this engine have a DISTRIBUTOR or NOT ?.

What was the LAST repair on the vehicle ?. ANY repair of any nature ?. In most cases problems that arise days, weeks or even months later can usually be traced back to the previous repair.
