Plugs and wire change nightmare
I haven't posted in the C4 section for a while. Actually I haven't driven my C4 in a long time either because of a bad miss. I knew it needed plugs and wires and maybe an Optispark. Well I got tired of looking at my dead C4 and decided to change the plugs and wires and hopefully have it back up and running.
I've done a lot of mods to the car in the past and I knew it was a PIA job to change them. I pulled the fuel rails, air pipe, dip stick holder, cold air induction, throttle body, drained radiator, removed alternator, unbolted A/C compressor, removed ASR, upper radiator hose, inner drivers side wheel well access panel and the serpentine. I raised the car enough to get under it. Now time to remove the plugs. I found out my Hooker headers have swelled enough that I can't get a standard spark plug socket on them so I ground down the socket to make it fit. Next I pulled all the spark plug wires off. Putting the wires back on was a challenge on the drivers side as I had a very hard time getting my hand between the engine and the frame to snap the wires onto the distributor. Anyway it took me the better half of a day to get the job done. The good news is that it runs strong again and it didn't need an Optispark!
Over the winter I put a supercharger an my C6 and even though it was a complicated job I don't remember any part of it being as aggravating as plugs and wires on the C4 and to change the optispark is just insanely over the top ridicules.
I will tell one thing though when I'm in the C4 with the cam hitting hard, the 3.73 gear pulling hard and the 3K stall converter doing its thing that car feel like a sports car. The C6 feels like an extremely strong Cadillac.

Plugs aren't too bad once you know the shorty cuts. The wires however 
.
You want hard? Try replacing plugs on an LT1 F-body. You need an assistant with small hands and a monkey.

I hate that the miles keep racking up.
