help please

[mentaleeill]

my 88 325e automatic just started to misfire. when idling it pops through the exhaust consistently like a pattern. i replaced plugs, cap, rotor, fuel filter, and airfilter all about 4000 miles ago, and also at the same tie put an i t.b. and intake manifold on it. what could cause this now?

misfire? ... check your wires. and plugs

You could try throwing a can of SeaFoam at it and see if it clears up.

ok, i checked the plugs today and found that 1-5 are in perfect shape, but 6 is black with a carbon buildup. also did a compression check and that was perfect. what could make #6 gum up with carbon? injector, bad plug? i tested to make sure 6 was firing and it is.

check the gap

[mentaleeill]

gap is right on the money. ran sea foam through it today and it's still doing it. any ideas?

Try naming your thread. Try something that relates to your question. It gets alot more views.

"Help please" is a sure fire way to get banned.

You've got 5 minutes to change the thread title to something appropriate.

You made me waste my time coming here. If you put it in the thread title, we can tell whether or not it is something we can help with.

I'm playing good cop and added a description to the secondary subject line, it's perfect, utilize it.

Compare the plugs in the bentley vs your misfiring plug, is it oily or just fouled?

Check valves, adjust if necessary, and check your plug wires. Get ready to cough up cash since they're a pretty decent penny for good ones (~180).
