Yet another surging problem
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. ![]()

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. Jim

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.
