distributer problem fix?
i finaly found out why my engine runs funky. throwing codes for a random muli cylinder missfire i changed out all the parts i thought of and no result. after months of trying to figure this out i got a tip from a friend who said to check the distributer shaft and see if its loose. bingo.. the shaft is loose. would anyone happen to know how to go about either tightning the shaft or replaceing the distributer? I have been reading though a few things but they are unclear with what exactly they are doing and i am not to familiar with the specifics of the system

Only fix is to replace the distributor. It's honestly not that bad to do. I was very skeptical about doing it myself after reading around a bit, as most write ups make it sound pretty hard to do. Here's what you do:
1. Take lots of pictures
2. Take a picture of how the wires are ran (so you'll get the firing order right when reinstalling)
3. Disconnect wires from cap and take off cap.
4. Unplug the Camshaft Position Sensor
5. Disconnect wire from spark plug #1 and take out spark plug
6. Get a wrench on the harmonic balancer and turn it clockwise until compression is felt in cylinder 1 (with your finger covering spark plug hole)
7. Take a picture of the position of the rotor at this point.
8. Take out rotor and CPS
9. Unbolt the 1/2" bolt holding the distributor to the block and remove entire distributor
10. Put in new distributor and get the teeth to mesh so that the rotor is in the same position on the new one as the old one you removed. This may require you sticking a flathead screwdriver down into the block and turning the oil pump. Also, make sure your gasket seats nicely at this step.
11. Put on CPS, rotor and cap. Reinstall spark plug #1 and reattach all wires in the proper order.

is there any specific brand distributer to stay away from or to buy?
