Spark Plugs Changed this Weekend
My car was misfiring at idle for the past few weeks, and I got a P0307 code. I checked the plugs and wires and thought it was time to give her a tune up.
So I performed my spark plug change yesterday. Took the strut tower bar off, so it was easier to remove the LS1 fuel rail covers and the coils. Pulling the spark plug wires out was a bitch and a half. Had to use a vice grip and a big screwdriver and used the valve cover as leverage to get them to pop off. Drivers side was pretty easy to replace the plugs. Noticed the V came with AC Delco Irriduims from the factory. Labeled each one I replaced by cylinder number on each plug box for future reference. Used TR5's gapped at .040". And used a liberal amount of anti-seize on each.
Then came the passenger side. What a PITA! Started with cylinder number 8 (rear passenger side.) I did not take the battery out like other had suggested. But the damn wiring harness that goes to the battery and the fuse box doesn't have much slack back there. It got done, but not without A LOT of swearing. I also did not have to take out the dipstick mount for cylinder number 4 like many others had suggested.
I used MSD plug wires. Frustrating thing about installing them over the plugs, is you can't hear them snap into place, so its hard to tell if they are fully installed on the plugs. So I spent a good amount of time trying to contort my hands in there to push them onto the plugs. Used a good amount of dielectric grease on each for lube to get them to slide over the plugs, and for future removal. Probably spent 2.5 hours doing the entire install from start to finish. A lot of the time was spent trying to find my 10mm deep socket that I lost somewhere in the engine compartment.
Got everything back together, hooked up the battery and took her for a spin. Throttle response was instantaneous. She feels a lot faster through the entire RPM range with the new plugs and wires.

Thats why I was curious. Haven't needed plugs on the V yet, but did have to replace iridiums on the wifes lexus at ~60k.
Wonder who actually gets to 100k on these plugs.

I did the wires but gave up on the plugs. Way too much of a PITA at the time. I just hit 80k so I really probably do need to do the plugs. Just would hate to tear an MSD without backups on hand

Changing the wires on the passenger side is a pain. It's one of the reasons why I just want to get a battery box and throw the battery in the rear. It gets old having to remove the thing every time I do a tune up.
