Stuck 500 miles from home. Misfire Cyl 6. Help!

[Elkman]

Did you clear the codes after the new spark plug? The DME will cut off the fuel injector to a cylinder that has multiple misfires, clearing the code will turn it back on.

I would get a free code scan at autozone to see if there are any codes. How did you determine it is a misfire on cyl 6? I would be reluctant to throw too may parts at it. without diagnosing. It really could be anything.

Also you can borrow a compression tester from Autozone /Advance Auto, etc. for free.

Inspect intake boots.
swap coils with neighboring cylinders and see if misfire moves

As a back-up I would search for a "vetted" Independent mechanic in the area on BIMRS.org

You, my friend, just saved me having the car towed 400 miles with AAA, and having to jump through hoops claiming trip interruption from them.

Cleared the codes and we are golden! Smooth as buttah... But I did learn my compression in Cyl 1 is 160 and in 6 it's 120, so that sucks. That's why my plug fouled. But this will get us on the road again!

I owe you so many beers! If you're ever in Orlando let me know!

And to Effduration: I carry a cable and INPA on my laptop always, so I pull the codes myself and reset it as well :-)

Thanks for the tip on where to find a good BMW mechanic!

Glad I could help, I have gotten help here in the past.
I have a youtube link for you, Others and I have done this with success. He recommends 1 oz. per cylinder I used a lot more.
