so someone said it sounds like I may have lost a piston ring....? what simptoms are we lookin at for that?

thing is I pulled the car into the garage and it was fine. It sat for like 4-5 days and then when I put everything back together and fired it up it sounded like crap.

check the exhaust gaskets again. Is it louder in the engine bay?

A dead piston ring would leave LOTS of blue smoke coming form the tail pipe. Did you somehow crack a weld on the header at one of the collector points?

nope the header is fine. what else would leave me feeling low on power? The car isn't smoking, but the idle is really messed up even more than when my vaccum lines went out. What abour a bent valve or something? I am tryin to plan for the worst and hope for the best...

I would make a vid of it but my camera doesn't do sound

btw I am getting HORRIBLE gas mileage, like 15ish on the highway! and barely enough power to get up the mtn.

when is the last time plugs and wires were changed?

If you've already got the COP conversion...the dis-regard that.

My car used to run like shit until I realized that the plugs were FINISHED!

I do have the COP conversion. The plugs had carbon buildup on them from running rich when the o2 was dying. I put in new plugs a few minutes ago and its acting the same. One really weird thing is that the coil closest to the firewall is like melting some crap out of it? Its really weird, I'll take a pic of it later tonight. And that spark plug looked fine and didn't have carbon build up.

If a coil pack is "melting" or oozing, replace it immediately. It means that is it over heating internally and it will go bad very soon and in some cases catch fire. Most do not catch fire, however since you are using it in a non-intended way it may not have the over-heat protection and may catch fire. It could aslo be causing your engine problem.

Please please please do not take this warning lightly. I've seen it first hand and do not want your next thread to be "my car caught fire".

ready for the weird? That is the 2nd coil to melt like that....

both were in the same spot, the one closest to the firewall. This coil has only been in for about a week and its already starting too. Any reason why one would do this? Much less two that fast?

I am considering selling all my turbo stuff and goin x50/52 soooo heeeelp!!! I love the m42 but I am just getting frustrated w/ it.

I don't know why you would be losing coil pack so often. I'd look at heat in that area (from header or trans or being directed that way) or a bare wire.

sounds like something might be shorting out... or that it is getting commanded on all the time and overheating? maybe its not grounding through the right path. It could possibly even be caused by the plug? did you change the plug as well when you swapped the pack the second time? and just double check your wiring too that coil pack maybe something is a little funky...

Seems like it could be related all right....
