(First of all, THANKS, DANE! for helping me with removing coil packs via FB chat! it was a PITA)

So I hope I didn't create a NEW problem while trying to troubleshoot another.

So I got a P0302 code (misfire Cyl 2 ) with CEL and shaky idle, and I was going to to swap out coils 2 and 3 if the Code moves to #3 cylinder to make sure (if) it IS a coil pack.

I had trouble getting coil pack 2 and 3 out so I tried coil 1 and it came out really easy BUT when I finally got the coil 2 out to swap with it, I noticed that the coil 1 looked different than coil 2 and looks like its (coil 1's) boot was missing? did it stay with the plug?

SEE PIC (Coil pack 2 on left (normal) and 1 on right)

what happened there?

anyway, I pushed it back on to the same cylinder, and finally got 3 out. (looked normal, like 2 )
So now, I swapped 2 and 3 and started car - same symptoms, shaky idle but RPMs steady - BUT NO CEL yet -
so I guess It will take a few drive cycles for the CEL to come back on?

(BTW I erased the previous code P0302)

So, as of now, expecting CEL and expecting it to be P0203 which will show me it really is a bad coil on Cyl 2.

But in the meantime I am worried about why that coil pack #1 looked weird as if something is missing from it. it's all hard plastic and looked like the rubber surround was missing. ???

It was also a bit wet...
Anyway, I pushed it back in, and it felt like it seated well. I hope it will continue to work as before..

From a quick search I did, I don't think one can buy these boots separately if needed. (Bosch) . One CAN buy separate boots for Bremi coils (up to 2003), apparently. ECS tuning chat could not find a separate boot for Bosch.

If I don't get any UNEXPECTED codes for cyl 1, due to the boot issue, should I just leave it alone? or would you change it due to the little wetness I saw? there was no oil to be seen in cyl 1 hole, but I am thinking something must have made it separate from the boot so easily...

Oh, Can I drive the car around without the left part of the engine cover?

Yes. The boot stayed. Yes. You can drive without the cover.

Thanks again!

Yep - Sure looks like it - one can see a black surround around the SP in that plug hole.

Drove car around - no CEL yet. Seems almost normal while driving, but idles weak-ish. RPMs at idle steady.
Car def. has a bit of power loss uphill. One can hear a change in the engine "tone" a few seconds after car starts.
Probably will require more driving, overnight off, etc for the SES come back on. I have no clue what kind of drive cycle is needed on these cars for that.

Can this thread be moved to mechanical section? I posted in maintenance by mistake. Thanks!
