Plugs getting fouled

[inthexring]

So I am on a ride the other week and all of a sudden I start missing.  Never happened before and I am about at 30,000 miles.  Never changed the pugs either.  So I get home and changed plugs and it works great, lots of power.  Thinking I must have fixed the issue.  Three weeks go by and I get the same thing.  Anyone experience this?  Know of any good fixes.  I am gonna try some ring out, and get all the oil cleaned out.  Just wonder if there is a bad issue or just time to do some maintenance.
Thanks

What did your second set of plugs look like when you pulled them? Oil on them?

if you can post some clear closeup pics of the plugs you just pulled, I (or a lot of other folks here I'm sure) can tell you EXACTLY what the issue is. Or, barring that, they can at least get you pointed in the right direction.

Sounds like a dirty airfilter....put a new one in.

I will change out the air filter, I can't see thru it, but I had it run with out it and it didn't get better, here are the plugs, I pulled them out to take a look

ummm...yucky, u running rich?

[SpeedAdict]

I hope it gets resolved for you. Have you ever gotten your valves adjusted? Might be blowing a little extra oil in there.

Looks pretty rich. Bottom left looks a bit oily, but not too bad. Find out why its rich. Check the vacuum line to map sensor, test the coolant sensor and tps. FI light on?

FI is not on, Lately I have put a power commander and takent he Pair valve off, I better go over everything to check it out. It is running really rich, I better read up on on to adjust the power commander. Maybe I can try a few different maps.
Thanks

I would say then your map is too rich. (since you just installed the PC) I would just try it without the PC, if it runs good (not rich anymore) then you know those sensors are working correctly.

Its been a while since I've been into my PCII, but I thought it displayed atleast the TPS. Maybe even the engine temp? Sorry, don't remember, and its a PCII not III anyway. (99 750)

Got a new set of plugs and put on a new map, runs like a champ, just waiting for the new air filter now, should be arriving in a few days. Maybe I am good for another 20,000 miles

Double check your vacuum lines, sensor hook-ups. I had a vacuum line pinched under the airbox once. GL.
