Help friends - Just replaced the plugs, distributor and ignition rotor in my van. After I put in the plugs I started the engine to listen for misses in case I had not gotten one of the boots back on. It ran without a miss.

I then pulled the distrib cap and replaced the rotor and I think I did a really stupid thing...The rotor is held in place with a screw which was facing the back - difficult to get to. Without thinking, I bumped the ignition to spin the rotor before I realized that may not be a good idea.

Regardless, when I looked at the rotor again, it seemed to be in the same position so I thought no harm, no foul. I went on with replacing the old one and putting on a new distrib cap and started the engine - missing like crazy. Starts but barely runs, shutters, etc.

What did I do and how the heck do I fix it? Do I need to set the rotor to TDC by rotating the crank and then put the distributor back on????

HELP Please!!!!!!
