hey guys lately i been getting a CEL.......i went to go get it scanned and all and i was told that i had a misfire in chamber 2.......i went out and bought me some new spark plugs Bosch Platinum 2s and turned off the CEL with the scanner........everything was goin good until tonight when it came back on.......so right now i got the CEL along with the Trac and VSC.......im thinking that i should go buy a new coil pack and replace the one for chamber 2.........but i dunno which one is chamber 2 haha it has to me one of the ones in the middle ether the left or right one in the middle...........any thoughts on the matter?

 

bosch plat 2's , and 4's are horrible plug which will go bad.

 

its onlee been like a month or less

 

Do you still have a warrenty?

Service department can give you the fireing order so that you know which one is #2. Should be second plug from the left(front of engine), but make sure before replacing. I would make sure it is the coil as well before replacing it. I had to replace one of these indivdual coils on a Lincoln LS and it cost $56.

P.S. I see that you live in GA, I will be moving to Augusta in a couple of weeks.

 

Can the coil packs be swaped around to see if it changes to a diffrent bank?
That should tell you if it is a coil.

Like krazyhorse said, swap the coilpacks around.

And make sure to clean around the bolt area, or run a ground wire to the coil pack bolts to head. I had a miss and corrected it with one of those " snake oil", doesn't do any thing ( acording to some) grounding kits.

brand new plugs can sometimes just be bad, stick with Denso or NGK plugs and it should clear up.

 

ill try to swapping the coil pack around and c if i still get a CEL.....i was told by da guy at the dealer that a new coil pack is $90


P.S. hope you like it in augusta.....thats like maybe an hours drive from atlanta give or take

 

Any news on the problem ?

 

well i just reset the ecu and switched the coil pack for chamber 1 and chamber 2 around now all i gotta do is wait for the thing to pop back up again........all i can do is wait

 

alrighty months later after the coil pack switching from Chamber 2 to Chamber 1 i've havent had any CELs and my box has been going strong ever since......i dunno what was up with the misfire but im glad its gone and done with.....

 

well my CEL came back on......the O2 scaner said i had a misfire in chamber 2..........so i will be going two steps colder on my spark plugs and hope that fixxes the problems........if not i will step up my Octane..........so gotta stop racing..........

 

lets c i have one bad coil and a misfire in chamber two........what luck i have.........

 

Throw the stock plugs back in and get it fixed under warranty. After that take those Bosch garbage plugs back and get a refund. Then get some NGK Iridiums and gap them at .044 and live happy with the 2-3 mpg gains.

 

warranty went bye bye after i got i/h/e/clutch/pully/ 70Kmiles haha but what went wrong was that two wires that was connected to coil broke off somehow ao i took it apart and fixxed it so da box runs fine now........luckly for me i've worked with wire harnesses and wiring for 3 years or else i would have been out of luck with having to possibly gettin a new engine harness cuzz mines was crap........

 

Glad to hear it was a relatively easy fix. Good deal!
I say still get rid of those plugs tho. Seriously!!!

 

i misfired with the NGKs more then i did with the bosch.....but when the bosch plugs go out well more like when its time for my oil change ill throw my NGKs in and c how things go from there with the fix and all

 

when u put colder plugs in u will get a misfire every once and a while at low rpms. Doesnt hurt anything so don't freak out. Dont put colder pluges in unless ur boosted or spray. No need to.

 

im not running colder plugs now but yea i didnt/dont get misfires in low rpms it happens in high rpms
