Yet another surging problem

[Kaliv]

Yesterday after work my car was giving me a little surging on start up that cleared up after getting out of the 25 mph zone. Usually not a problem, but it was odd that I was seeing this in the middle of the hot day instead of the cold morning. Got up today and after about 5 miles still getting surging even at 55 mph. I stopped and the car stalled. Babied it back home and took something else to work.

My first thought it that perhaps I have a vacuum leak or something is wrong with the mass air flow. What should I be checking to trouble shoot this problem down?

As a distractor, I did change my oil two days ago. I say it's a distractor because I don't think it has anything to do with my current problem, but I could be wrong. Emptied the oil and some white tapioca comes out. Not a lot but I noticed it right away. I'll post pictures later when I get back home.

Track back a year ago I'm chaning my oil and I notice all this pudding type stuff at the oil cap. I search Pelican Parts and there's a thread just about this. Can't post the thread because my work is blocking the search function. Apparently it's condensation and there should be no problems as long as it's not actually in the oil, which it's not. I had been running Brad Penn 20W-50 for three years in Nevada...but having just move to Alabama, humidity just isn't liking Brad Penn...so I switched to VR-1 Racing 20W-50. This is the first time removing VR-1...and I think the tapioca may be some residual Brad Penn coming out. I put VR-1 in this time as well.

When it hunts, leave her on and pop the lid, take a screw driver and tap on the ICV, if it clears up, then you need to remove it and clean the innereds until carb cleaner comes out clean then spary a bit of silicon based lube.

While you have it off verify the OHMs per bentley.

At first I thought I had some seperating ethanol gas, vacuum leak, or oil issue. I also check the ICV (which was replaced about 2-3 years ago) and tapping on it did nothing. So now I think I'm down to looking at the ignition coil section. For some reason I thought creating a new thread specifically about ignition coils would be a good thing...so I'm continuing my troubleshooting in that thread. But I didn't want to leave this thread unresolved...so here's the link to continue my troubleshooting.

Test Ignition Coil

there's several things that can cause surging in a DME 3.2, but I doubt that an ignition coil would be one of them.

Forgot to post pictures of the oil like I said I would. I circled some of the clumps I was talking about...picture is pretty bad...but you get the idea. And yes, that is the mess I made when the oil hit my hand taking off the bolt.




And this is the thread I was referring to that I couldn't look up at work.

This is disgusting - yes there are photos.....
