engine shaking on 91 626

my 91 626 had a broken thermostat screw so a guy came and heated it with a torch...then once we started it now its all shaky and stall at times it is not drivealble could it be that with the heat the distributer went bad...any ideas are appreciated....

the best way to find out whats not working is check the spark plugs and wires. if their not getting spark on all 4 or 6 cylinders then the car will not run good or will not run at all.

I once had a car where it was garaged for the winter and i replaced the plugs and wires and got cheap wires and one was too long and i started in the spring and it ran crappy and stalled. looked under the hood and found the wire got chopped up by the fan and the one of the other wires would not let current through. One of the new plugs broke from me barely touching it. turns out the caddy was running on 5 cylinders out of 8!!! Assume nothing works unless you can prove it.

hope this helps you out!
