distributor replacement

Just got a new distributor and before I jump in and tackle this just wondering if there is anything I should know. 92 yj 2.5.
And does anyone know what I should set the timing at. My plan was set at TDC #1 cyl set rotor at that and drop it in and adjust. I haven't put a distributor in for about 20 years so just want to make sure it's that same. Thanks for being understanding.

Pull the cap and mark the rotor location on the distributor. Watch as you pull it out to see the direction it moves. Put the other one in.

just so you know on the 2.5 the only adjustment you have is when you drop it in.. the body of the distributor has a notch so it cant rotate. Be aware of this when your dropping your new distributor in.

So as long as I watch where the rotor is pointing then I should be all set and no need to adjust anything.

it has to point to the exact point when its fully seated. As I said, there is no rotation on the outside housing of the distributor when its in place. Just keep this in mind when you install the new one.

That is exactly what I meant. Yes. If it points to the same place you dont need to go to #1 just pull it and drop the other one in.

Just replace the Dist. today along with new cap and rotor. seems to run ok it has a little skip it seems like at an idle. so is there any way to check the timing on the motor to make sure it is ok. I do see a timing gauge on the lower portion of the motor but don't know if and what it should be.

Its ecu controlled. I would check your injectors , plugs and wires first.

Not really. it can vary a bit. tooth one way or other and the computer will adjust timing. I did experiment and moved it back a tooth and forward a tooth. Both times it ran the same.

It shouldn't run the same. If you throttled it there should have been a difference. Pull the injector connector one at a time and listen for a difference I the way it runs.
