Well, The Avalanche is probably history. Had it scanned, and after fooling with the 4x4 selector switch, (engine running, trans in nuetral), a couple of times, it was back on. The seller doesn't seem very concerned about fixing it. Screw it. As for my Z-28, number 3 cylinder had a misfire. I checked it with my IR gun and I found it was less than half the temp as the others. The guy that scanned it said it was the plug. I have never paid to have plugs installed one of my vehicles. This particular shop has been a bit slow lately, and the owner said for around $380.00 he would change all 8 plugs and the wires. (I trust the guy), but does that sound high? Just curious.

You didn't mention which motor you have, but assuming it's an LT1, that's not that bad. I've heard of places charging a grand to do plugs/wires on an LT1 cause it's such a time consuming bitch.
