i have a feeling my #3 coil pack isn't firing after spark plug changing... i snapped the bold holding the coil pack down..

my question is.. does that bolt ground the coil pack? the bolt snapped off flush with the valve cover.. i'm on my way to the hardware store to get a kit to remove that bolt or drill and re tap the bolt.. any info would be nice..

i've heard of people running the coil packs with no bolts in them at all and jsut leaving the coil pack cover on and it holds them down.. however i don't think this is the case for my situation.

 

i extracted the remains of the old bolt and reinstalled the coil pack... the car ran great until it wamed up... after it warms up the car goes pig rich and dies.. going to pull my O2 sensors and clean them to see if it clears up any issues.. anyone with this experience would be nice as well.

 

unplugged the o2 sensor and after about 10 minutes of driving and idling around the block it started to dump fuel and stalled.. when i went to start it back up it sounded like it was only running on 2-3 cylinders... this is all so sudden.. i replaced a turbo gasket, checked all of the couplers, and changed my fouled out spark plugs..

now i didn't check the gap on the plugs but i'm running NGK BKR6E plugs and i didn't have to gap the last set and they ran hard for about 30k miles until i had the gasket blow and foul them out... the plugs seemed a big burnt as well on the porcelain part... burn almost hafl way up the porcelain. maybe just a coincidence that i have a bad coil pack?

need this fixed in the next day or so.

 

ecu 62 throwing code 34.. knock sensor. would a knock sensor cause this problem?

 

i reset the ECU.. and it throws 55... "everything ok"... i ran the car for about a minute or two.. shut it off, put it back into diagnostic mode, and got code 55 again. is this something that will keep coming back?

 

it will come back... i think i have a spare knock sensor if you need one, they're a PITA to get to though... i'd take a look at your CTS too, those will make cars do some weird random shit if they're bad.

 

No bolt does not ground the coilpack. Yes knock sensor will make it run pig rich. Knock sensors get old and crack its a common problem.
