Im new to landyzone, and need help!

Hey guy, and lady's if there are any. I have a 2001 p38 and have an issue that just rose Friday after work. When pulling away, I had a sudden loss of power and some noise the sounded like an exhaust leak. My immediate thought was head gasket break from the cylinder to the outside. Rough idle, poor bottom end, okay highway, no plumes of water through the exhaust. All noise coming from bank of 2,4,6,8 cylinders. Ran a diagnostic and it read #1 cylinder misfire. Checked and sure enough, no fire on #1, excellent on 2-8. Checked the wire and the wire was good, tested work through #7's wire hooked to #1 on the coil and still no fire. Can a bad coil pack only affect one cylinder? My thought was a bad coil pack would affect all cylenders it supplys power to. I'm lost, please help.

Bit confusing how you wrote it but think I get the drift..

basically your saying num 1 works when hooked up to one you knw works??
Well in that case its your coil pack as you thought... when a coil pack goes it wont shut all down just the bit that goes, snaped wire inside ect ect...

does number 1 wire work when connected to one of the other ones you knw work?

Thanks discocheese, yeah it does work. I ran numerous test and came to the same conclusion. Ran an ohm test on the wire and it's fine, disconnected #7 wire which was firing when connected to #7 port, connected it to #1 port and it failed to fire off that port, which told me it was in fact the coil. That's where I got confuse, I figured a bad pack would affect all associated cylinders, guess that's not the case. Still doesn't account for the noise from the other bank. I attempted to run a compression test, but the treads on my compression tester were too short to reach and thread in. Something tells me I may have two seperate issues, cause when I pulled #1 plug, it looked like it hadent fired for a while, and this just happened. Who knows, gonna try and find an adapter and run the compression test just to rule out the h.g. failure, and hopefully narrow it down to just one problem, which of course is a lot easier on the pocketbook, and the knuckles! Lol
