What size and type are the replacement plugs and wires for the 1995 gtp(grand prix)?


I have used all brands of spark plugs over many years...the AC Delco Platinum tip proves best for your Grand Prix...also use high quality plug wires not the cheapest (do not recommend Bosch plugs or wires...many issues of breakdowns) Ask the parts person what the plug gap should be, and measure and confirm this on each plug prior to installation...also highly recommend you use anti-seize libricant on the threads of the plugs...also recommend use electrical lubricant when installing th new wires...best for sealing and future service:)

I've got a 1995 Pontiac Grand Prix that started running rough. I replaced the spark plugs and wires, but it did not solve the problem. what do I check next?


You need to check the coil packs, if there was corrosion on the plug wire terminal when you removed the old wires that coil is bad. If that checks out pull the EGR solenoid and make sure there's no pieces of carbon stuck in the plunger
