Could an old distributor rotor (130,000 miles) be makin my car run kinda crappy? Like hesitation and ****? Just curious.]

yes it could... take it out and have a look at it, or better yet put one end of a multimeter probe at the metallic center of it, then run another probe down the length of the blade (the skinny edge that passes the distributors "points") - if you get intermittent continuity I would consider replacing it....

mine (as seen somewhat blurry in the link I provided above) was quite coroded.. only about 1/3 of the blade was conductive. this can lead to misfiring..., or a lower intensity spark ...which sux.

test the cap continuity from the plug end thru to the points inside the cap, also - look for cracks in the cap...

It's monkey proof so you can't screw up the installation of a new rotor (as long as you haven't taken the drive end a apart)... new rotor's are also cheap - so it's a recommended job
if you don't have a timing gun yourself, mark the timing of the distributor to the block, before removing the distributor - OR, just remove the cap, and leave the distributor mounted. I like to take everything apart and look at it, so I usually take the whole thing off...

if you read my entire thread above - you'll see getting your engine timed correctly might help your hesitation and crap running.

Best of luck.
