Installed New wires and plugs high idle
I install a set of NGK tr55 plugs and msd wires. Thye plugs are set at 055. The Ac delco plugs were all gapped at 65 to 68 when i took them out. so it was time. the car has 68k. The problem is now I have a high idle but no misfires the car run good just has a high idle. I cannot find any loose vacum hoses. all coils are tight and wires connected good.
