THANKS TJ it runs alot better with the new points in it. Any recomondations on a exhaust, mine is in need of a new one.

Funny you should mention exhaust. Check to see if you have a leak around the exhaust manifold or the EGR tubing leading into it. Mine had some of the worst backfiring I've ever seen after the tube split a little on the way home.

I was limping down the streets litteraly apologizing to the neighbors

Id go with a free flowing muffler and try to keep the stock diameter exhaust piping.

Why would the points affect backfireing? After reading that I'm going to change mine since mine backfires from 3rd to 4th but whats the correct point gap for an '80 1.8?

A hole in the exhaust will make it back fire.

So will a burnt valve, but this is unlikley on a crossflow motor.
