Mike, You need to adjust the 02 / Mixture screw only when a new 02 sensor has been replaced and the car is ( Hot ). If you don't have a new 02 sensor then your adjusting to an old one can take it to far out of adjustment rich or lean. I also recommend that you put the 3mm long handle wrench in the hold until you can feel it set in the hex head and turn it in small baby steps and not taking it out as to loose your clock position. Hope this helps if it's not to late. You could have a low spark situation or plugs are gas fouled.

I turned the screw a little both ways and while doing that the engine would shake and want to die. I turned the screw back and it recovered from dying, then when I tried to smooth it out, it started shaking again then died before I could turn the screw back. Now the car won't start. I tried a few times later on because it seemed like the engine was getting flooded. I tried to start it after sitting over night and a few other times and it will start for a second then stall out. I have the battery on a charger because I could see the volts going low from cranking the engine, so after the battery is charged up I'll try starting it again. Does it sound like it's not starting because the battery was low, or because I turned the mixture screw too much? It always started before I played around with the mixture screw. Any help, suggestions greatly appreciated!
