PONTIAC GRAND PRIX COMPRESSION PROBLEM

2000 Pontiac Grand Prix • 140,000 miles

The car stalls and tries to die at stop signs. I had a diagnostics test on it and they tell me that the #1 & #3 plugs are not firring properly. I have replaced the plugs and the plug wires. Is this a coil problem?

It cold be but have your fuel pressure checked first. It can also be a compression problme.
