Hey there,
So, I have been fighting misfires forever.
I believe that I have figured out that it is my plug wires.
With a little help from younger ears that can hear high pitch snapping noises, I found a plug wire that was arching against the exhaust manifold.
The question is; WHY! They are only 4.5 years old and about 30,000 miles on them.
The bigger questions are; what's up with the two straight boots and four 90 degree boots? Which plugs are suppose to get the straight boots and why?
Any wire suggestions? How about these,

Thank you

Re: Spark Plug Wire Boot Question
Those wires will do fine, maybe a little better than stock. Just watch the routing. That is the reasoning behind the mixed boots. If you pulled the original wires you would see which goes where. Sorry I can't help you on that as I haven't had a 6 cyl astro in a few years.

Re: Spark Plug Wire Boot Question
I've recent experience with the secondary wires on a V-6; my 1997 M11006 is equipped with the Vortec 4300. The shortest and longest wires, which go to the foremost left (#1) and aftmost right (#6) cylinders, respectively, have the straight boots as a hedge against burns of the wires themselves due to the design of the exhaust manifolds. With the high-voltage switch, the second-longest wires should go to the fore and middle right cylinders (#2 and #4); the second-shortest, to the middle and aft left cylinders (#3 and #5).

So, interesting development .....
I installed the Accel wires. They do look cool and fit much better than the Blue Streak wires that I replaced.
The interesting part is that when I pulled the coil wire off of the cap, the pin in the cap came out with the wire.
Running super smooth now!
