Well, I think that I figured out why my car idles like crap, and failed emissions miserably. I replaced my O2 sensor friday night and I replaced a few vacuum lines. After I got finished, I started the car and the garage was dark. One of my spark plug wires was arcing about 1.5" to the intake! I ordered some taylor wires from summit, they will be here on Wednesday and I can hopefully pass emissions.

 

I hope you have an ecu!

Is it arcing from the wire itself, a boot, or the plug? It can arc if it's not on the plug good or it may be cut/no insulation.

 

It's arcing right from the boot on the coil pack side.

 

Dielectrical grease...

 

That may not be the cause, it could be the result.

Check the equivilent of the distributor. I beleive it's called the coils.

 

happened to me, move the groung wire to another location, will sove problem. that or make sure boot is on perfecty. my magencor boots slip a little, evey once in a while I haev to push back on.

 

Move which ground wire?

 

for the coils, rip off UIM, look at coil packs, and you will se ground wire bolted arounf plugs
