!st Time Changing Spark Plugs!!
I've got an 02 with 9500 miles and a NOS system. It's a wet system with a 75 shot. The only time I tried it at the track the engine started bucking for a lack of better terms. It all happened so fast. I let off the gas and the engine shut down until I turned the chip off of the NOS program and restarted. I called REM who did the prgramming and his first suggestion was to check the plugs. I decided to change them out. REM suggested TR6 with a gap around 30-35. They said they change them out all the time without removing any fuel rails. I have lot of tools, so sat. morning I started on the pass. side. Being the first time I was a little nervous of the process. The pass side took me a little over an hour. The driv side took me almost 3 hours. Most of that was on the back two. Here is what I found and what I used to do the job. Maybe someone can enlighten me on an easier method. The coils are 7mm and the plugs are 5/8". Make sure your spark plug socket has good rubber to hold the old and new plugs. I also disconnected the injector connectors to gain more access. The plugs I removed were TR6.
P-1, gap was .043, coil-used 1/4" drive with a 3" ext, plug-3/8" drive, 9" ext
P-2, .045, plug-3" ext, univ, 6"ext
P-3, .043, plug- 6"ext, univ, 9"ext
P-4, .043, coil-univ, 7"ext, plug-2"ext, univ, 15" ext
D-1, .043, coil-12" ext, plug-6"ext
Removed the PS resevoir
D-2, .044, plug-3" ext, univ, 15" ext
D-3, .043, plug- 6" ext, univ, 15" ext. There was a piece of plastic wiring bracket in the plug hole. Prbably took 40 min to get out.
D-4, .048, coil- univ, 3" ext, univ, 16"ext. Couldn't even touch the coil bolt. Had to use a magnet to remove it. Plug-univ, 15" ext. To put the coil bolt back in I had to put stickum type stuff in the socket to hold the bolt to get it back in the hole in the coil. Unless there is an easier way, the changing of those two rear plugs on the driv side is a real nightmare.
How were those used plug gaps? The burn color looked good but the V notch was worn away somewhat. I tried the NOS for a short period, 4-5 sec. Haven't tried it for a 1/4 mile yet.
