arcing under the hood, etc..
ok i just replaced my tps in an effort to track down a strong miss/shuddering upon acceleration.....its better but not perfect
i read on here about checking under the hood in the dark, and boy did i see some fireworks, oh btw i hear the "ticking" sound too....which made me want to check it even more
i can see every so often the coil is arcing, as well as a couple wires where they touch the metal,
1) does this mean i need a new coil?
2) does this mean i have to replace my wires, or if they aren't burnt or split just reroute them so they don't touch hot metal?
3) i'm gonna check each one tomorrow for resistance values, as well as inspect for cracks, might even check a couple plugs while i'm at it,
oh yea, in the process of all my tinkering, the little plastic factory clips that held all the wires in line broke or got lost a LONG time ago, so whaddya'll use to properly hold your wires in place, away from metal??

Suggest that your primary issue is the plug wires.
Checking them for resistance will not be a 'go' or 'no go' as far as their integrity to a ground. Re-routing may be an option, but if you're seeing arcs, suggest to replace the wires - get good ones - have had bad experience with the chain parts stores discount offerings - such as 'Duralast'.
As far as the clips, it's good practice to avoid crossing wires in straight runs. There are replacement clips available - the 'HELP' line of products is available, as I'm sure there are others. Perhaps not exactly stock, but functional to keep the wires properly spaced apart.
Also suggest to hold off on the coil replacement until the wires have been changed.
At any rate - there should be no 'fireworks' visible under the hood - suggest you're on the right track, further suggesting to fix one problem at a time in efforts to save some bucks as opposed to a blind 'replace everything' approach.

I agree, sounds like a problem with the wires. You need to get a good set of 9mm wires. I know with my 93 with a 302 has an exact way that you are supposed to route the wires. If done incorrectly, it can ruin an engine. I have heard of people frying engines because of it.
