I thought I tried ever-thing to resolve my multiple cylinder misfires and had no luck. I actually started a thread questioning the boot on a new OEM coil pac. Why is the spring inside different than the OEM - I never got an answers from anyone - it got real quiet all the sudden lol. Maybe know one knows. I put all the very old OEM boots (8) and there special copper/brass inserts that you can't purchase anywhere (with the exception of a few salvage yards) , back on the coils and what a difference - like night and day.. music to my ears. Sounds very healthy now.

 

Congratulations jbrew!

Now I can post this picture of my COP spring and offer you some help with your problem... Oh wait. Its fixed!

 

Well ya just popped my bubble temp1, so is that an OEM spring ? My trucks running good - don't jinx me !! lol. Ok, so maybe I hoping that over-positive thinking will wisk my misfires away. For the last couple of days it has been running well, on 92 octane(high test and SeaFoam-lol) My truck hasn't hinted that it still has issues. I'll enjoy it while it lasts and hope it was in fact the boots. Time will tell - usually does ( :

If I by chance find a pic of what's inside my OEM boots, I'll post it - way different than your pick - was your truck manufactured in 98 or 99? Mine says 07/98 - which is when they went to COPS I believe..

 

My truck was manufactured in 1999. If I remember correctly mine have a spring within a spring and some metal type thing that can move inside one of the springs.

Look's like I have to take a pic of the insides f my cop boots (more complex) - hey did your truck get recalled recently?

 

Yes, I had a recall on the cruise control problem. It was fixed in february I think.
