I used my digi cam to record some stumbling as I applied some very light throttle. As I applied the throttle slowly the rpm's would drop and come back up. At one point the rpms went close to 0 and almost stalled, but came back up. Does it seem like a vac leak?
Anyone know where I can upload the avi files?
Also, I have a video of my car shooting out a drizzle of water when I had the a/c on full blast.

Sounds like a vacum leak. You didn't by chance remove the intake assembly recently? I had mine off the other day and put the clamp that connects the intake tube to the throttle body on incorrectly. The throttle linkage was catching on the clamp causing a slight stumple. Took awhile to figure out.
Good luck.

You got a major vacuum leak. I would check the vacuum hoses for the ISV.

This shows a picture of the vacuum diagram.

It looks like the vacuum hoses were replaced with silicon ones and zip tied. I'm going to need some local help to diagnose and resolve the problem.

It had the silicon hoses before I bought it, but I never really noticed the stumble until now.
IIRC I did it during both cold and hot, and the same thing happened. If you look at the video you can see the temp guage (or maybee not). The stumble happens when I give it very light gas. I put my foot on it slowly and gently ease it in and it begins to stumble like that. When the car is idling normally nothing out of the unusual is happening.

maybe it has something to do with the arc2. i rmemeber my mechanic telling me that you need to adjust the low miud high and accel settings everytime the weather changes or else you risk running lean? Im not really sure but its worth a shot. Nice car btw, hopefully we can meet up sometime mines coming back from the bodyshop this week from paint.
