Default Dies after high revs!

Previously a loose wire in the coil caused my coil to blow out the sides and the car wouldn't run. This morning I remedied that with a new coil and plug wires. Car started up and "drove" fine. Problem is, when I let off the gas for a stop or a turn, the Alt (oil and brake follow) light comes on and the car goes into stall mode. Sometimes the car will catch itself and give itself gas and ossilate between stall and 2K rpm until it gets back into a nice idle speed. Other times, like when I'm moving, I have had to restart the car.

I am runing the MSD with proper Blaster coil and Magnecor wires now. Might it have something to do with all the "tests" I conducted sorting out that problem?

Any quick ideas before I spend a lot of time searchin PP BBS?

The reason for the surging and probably for the idle dying is that the idle and/or mixture is out of calibration. O2 sensor tries to compensate with mixture variation which changes idle which in turn changes mixture.

I did some PP BBS reasearch a guy was having te same problem. Matt, I think you nailed it. I'm having a bitch of a time getting the tool in there though. Everyone says 3mm, but I swear I could fit in a 5.5mm allen key. What the hell am I doing wrong??
Arg!

I use a Snap-on allen P/N TAM3. I cut it down to 130mm total length. I initially start to feed it into the hole at a 30 degree angle. I continue feeding untill I hit the 3mm allen hole. Sometimes dirt will sit in the 3mm allen hole; I clear it by giving it a shot of air via a long rubber tipped blow nozzle.
