When you say the car is surging do you mean, by what you hear or your rpm gauge? Is it just during cold start? Have you cleaned your throttle housing body (replaced gasket)? If your car is running rich there could be many reasons....

Not sure about adjusting your AMM, never had to do it, hopefully someone else can help your there. You might want to post a seperate question for this so it is seen.

Glad to here the brick is going... though I am not sure for how long. That is if you didn't actually do anything to fix the problem. It may just be temp. fixed. For what reason I do not know, I have been having the same problem with my car. Works fine for awhile, then acts up again, over and over I have been going through this for months. I wish no ill will on your brick...

I'll be working on my car tomorrow. I have a list of things to run through. If I discover anything I will touch base with you again...just in case it helps you...
