Sorry, was going to post something here, then realized I missed a page or 2 of posts..

Im havn same problem. It is strange, that I also replaced all the plugs and wire recently before it acted up. The sixth plug was burnt up and not firing. Same thing now though with misfire after 2 on boost. I bought a coil and switched it to each one with no help. Did replacing all of them help, or just a waste of money? I hate that I have to g-ma a supercharger!

Have you checked the ignition module? I read on another forum that someone did this for a '98 and fixed problem. I'm not sure what it is, I'm not the best mechanic, but will look into it and maybe try it out.

Ignition module has been thoroughly tested. It'* fine. Will be putting the new wires on tomorrow. Compression test on cyl 1 is fine. If the wires don't solve the problem, the only thing left is the injector. Will let you know.

#1 is very close to the oil dip stick. Make sure it'* not touching and grounding out.

How did you isolate to #1?

You can pull a code that will say, missfire #1. But the best way to tell if your having problems with one cylinder is to pull the plugs and inspect. All 6 should look very close. But even a little black on the plug will indicate a problem.

Finally at long last. Fixed.

After the following:

ECT
Intake manifold gaskets
2 sets of plugs
2 sets of wires
new coil packs

Took it out pushed it from a dead stop to 120 foot on the firewall the whole time. No miss, no stutter nothing. Pulled like it should making between 8 and 9 lbs the whole way. Did it three times.

I may have a starter problem now, but the miss is fixed.

The only thing I have left to work on is the interior lights blowing the fuse. I think that is the passenger visor because the lid is broken and I can replace the fuse and the interior lights will work for a couple of days then the fuse blows again.

The air compressor in the trunk doesn't work when I push the button but the ride leveling system works, you can hear the compressor kick on.

For plugs I went with the autolite xp606, BWD wires and house brand coil packs. Running syntec with the lucas synthetic stabilizer.

Next the plans include a 3.4 modular pulley, CAI, exhaust (magnaflow high flow cat, magnaflow mufflers, resonator gone, and 2 1/2 inch pipe), power log, ceramic crossover, and retune with HP tuners.

What kinda whp should that give me?

Is there any one thing that seemed to correct problem? Also, what is ECT? I am considering just changing out all coils. I am curios about the gaskets. I have noticed where is seems I have had a leak around that point. I have to try to do as much or all the work if possible.

Test your coils before changing them. You can find most procedures in the tech info section off the main menu.

As for the LIM gaskets. We have a write up on how to change them and it should be posted very soon. Just taking care f a few small details to ensure ease of following the write up. Keep an eye on the tech info section.
