Spark Plug-Wire Issue
Today I finally got around to changing the last 2 plug wires and the drivers side plugs. I've had the TR55's in the passenger side for 3k miles. The car ran-drove great. Now the car has low rpm miss and I have no idea why. The 2 plug wires I changed I have changed back and the car still has low rpm miss. Anyone have any ideas?

Could be that when you installed one of the plugs that the ceramic part cracked. Pull off the last plugs one at a time until you find which one cracked. It happened to me with 2 plugs.

Figured it out. Drivers side plug by the alternator was frekin defective. Put the old A/C delco in and now the car is back to normal. Now I have 7 Ngk's and 1 A/C delco. Oh well.

You should ba able to bring the bad plug back and get a new one for no charge from where you bought them.
