Distributor position
So a few months ago I put a new distributor in my '96 automatic. To make a long story short, I was frustrated with the whole process, and even though I knew better, I pulled the old distributor without marking the position of the rotor. What a dummy, I know. So vaguely remembering the position, I reinstalled the new one, it started fine. At the time because of some other issues it was running like garbage. So if I placed it a little off I wouldn't have noticed. I still have a multiple random misfire code. So after doing everything I can possible think of to rectify misfires, I have a smooth but misfire filled idle, if that makes any sense. SO- if I pull out the distributor, move it a tooth up or down and fire it back up and see how it's running, could that be the problem? I've changed everything there is to be changed, checked compression, fuel pressure, injector function, etc. This is the only other thing I can think of!

Mark the number one plug wire location in the distributor, then turn the engine over by hand and line the timing marks up on the balancer and timing cover to 0 TDC, take a look at the rotor and see where it is pointing. If it is pointing 180 degrees off just turn the crank one full turn and recheck it, you should be pointing right at the mark you made on the distributor. If it's not, then you need to adjust the position until it's correct.

Tdc is when the mark on the damper is at 0 and the #1 piston is at the top of its stroke. The oil pump is driven by the distributor and the part you need to turn is under the distributor. Stick your flathead down in the hole where Tue distributor goes and you will find it.

For anyone else doing this I found that the easiest way is to put the motor at TDC, turn the oil pump drive to 11 o'clock. Then take the cover off the inside of the distributor and find the alignment holes. The 4.0 hole is the one furthest to the right if the holes are closest to the passenger fender. Drop a pin in the alignment hole. Drop the distributor in and as long as it drops right in, it is perfectly lined up. Pull out the pin, hook everything back up and you're good to go.
