Rich,

Let me start by urging you to spend some time in the "700/900 FAQ" feature (see pull-down menu at top of page.) And pack a lunch. There is a ton of trouble-shooting info there. However, here are some thoughts on your comments:

"The car does restart after it's been shut off but, takes about 5 turns to start" You mean right away? Or after it's sat a while? If it's after an hour or two it could be the check valve at the fuel pump. But you have other issues too, so that's just a guess.

"This AMM has a different adjustment on it than the 006 one that came out. The set screw in this AMM has two holes in it for special tool to be inserted into it, the old one had a regular flathead screw type." That's an "anti-tamper" plug. Someone drilled it so they could "tamper" with the screw underneath. It should come out with narrow needle-nosed pliers.

"1) Should I attempt to adjust the AMM ?" Not until you have good reason to suspect it, and know how to do it. I'm sure it's in the FAQ. I usually put a meter on the O2 sensor-to-ECU connection, looking for (or adjusting to get) voltage swinging rapidly between 0.3 and 0.7 volts (maybe an occasional 0.2 and 0.8). This is with engine fully warmed and idling, with no other obvious problems.

"2) Now that I have the car running ? Where should I go next to troubleshoot the surging issue ?" As mentioned, the FAQ is a good starting point, especially if Volvos are new to you. You could meter the O2 sensor (rev to 2K for 2 minutes to get the sensor hot first), just to see what it "sees". Close to 1.0 volt and little/no bouncing = Rich. Down near 0 to 0.1 volts = Lean. Bouncing in the middle = OK. No rapid bouncing voltages = probably a dying sensor. (the ECU makes rapid corrections to the mixture, the sensor should respond rapidly too.)

But I wouldn't adjust the AMM till other areas have been ruled out (Vacuum leaks, ignition, fuel supply & pressure, etc.)

Hope this helps,
