Engine paint

[Kevin325i]

Ok, so today I took out some high temp black paint to paint the cover over the timing chain. I did that got it sprayed decently.

I go to start the car up and it starts just fine, but when I rev it cause I noticed it seemed to be running kind of doggy, it's got that stupid stutter I had with the crappy plugs. So I let it run for awhile took it on the highway, ran like a champ.

THEN I went to move into the garage and the darn stutter was back. Maybe I'm waisting my time worrying about it. I didn't get a chance to go and see if it would run normal after a drive.

So anyways, could this be a direct cause of the engine paint? Possibly some overspray got into some wires or something?

There's no fault codes. Does this sound like a symptom of loose spark plugs?

Any ideas, I'm kinda disappointed cause it was running like it ussually does before I started painting. Maybe it's just coincidental?

I've got an idea, everyone look out.

Has anyone with a K&N filter had a problem like this? I'm thinking it's my AFM getting messed up by the filter oil.

Does your car have an air flow meter or air flow sensor? If it is a sensor type like on the newer cars it is possible that the filter oil is messing up the hot wire inside. But if you have the meter type like on older cars like I do on my E30 I don't think the oil will cause an issue, my car seems to run just fine with the K&N on it.

Well nevermind, it wasn't oil from the filter. I'm pretty sure my plugs are just fouling.

let us know how things turn out and what it is.

Ok, so here's the deal. Because I keep my oil as close to the max fill line as I possibly can so when I corner during my autocrosses I don't get any starvation, there's too much oil in the system for around town driving and the plugs foul.

This is when the electrode becomes covered in oil and conducts a poor spark, or no spark at all. If I take it for a run out on the highway, it clears right up. The plugs just need more than 200 miles on them also.
