EPIC Failure....

[BimmerFREAK09]

So I watched Dave's DIY vid on changing the plugs.... And decided its easy enough to try.
Took everything apart to the "T"! Changed the rear plug then the front plug and fronts end cap that connects to the boot broke on me. So I went and got another plug and put it back in without breaking it this time... Put everything back together and started it up and it's only firing on one cylinder. So I took everything back apart and checked the seating on the boots to the plug ends and they're fine. Put everything back together again and still no luck....
BUT NOW, as well as firing on ONE cylinder, when I turn the key to on... it sounds like a spark or a short? I'm not mechanically inclined at all!!! So idk what to do...

Your plug wire is either off at the coil, i hope not the plug itself or ill face palm. Or the wires themselves are bad. Checked plug gap, what type BTW? Is the broken plugs electrode stuck in the wire?

What year?

Just the regular 10r12x from the HD place close to me... And they said they were pre-gapped to .32... And I don't think the plug wires would be bad because it ran decent before the change, and no the electrode isn't still in the plug wire... And it's an 09'

Just because they are "pre-gapped" doesn't mean they are correct always check them and use the proper gaping tool for the plugs you are using

Key off kill switch on, wide open throttle. Turn key to on, do you hear rapid ticking? I thought the same, my front wire seemed ok but turned out it at times it would arch, changed wire no issus. Never trust a plug to be pre-gapped. You could have damaged wire unknowingly when removed.

I'll do that tomorrow... I had to leave the bike at the the shop... Tried maybe baby-ing it home but had no power to go anywhere...

 

[user_deleted]

all good info above and it is either your new plug or the wire. logic dictates that whatever sparking component you messed with to do the job was disturbed and has failed. can't be anything else. and for what it's worth...if you have to remove the plugs again for whatever reason, put a very small dab of anti-seize on each plug thread and reinstall. you'll be glad you did.

Did you put the die electrical grease on the metal contact surface? Or on the porcelain side of the plugs.... remember the grease is an insulator... not a conductor so dont get much if any on the metal contacts

 

[BimmerFREAK09]

I didn't put any lube or grease on em... And idk... I could've pulled the wires from the coil but idk how...
