Okay i need some major help, I'm working on my fathers 83 245DL with a manual transmission, That was missing & dieing....when i popped the hood, i found a melted distributor cap, as in where the coil wire goes in the cap, It is melted where the button sits on the Rotor. The Button is completely gone & it is melted from all the arcing onto the Rotor. No i never found the Button or spring.

So i replaced the cap & button, along with the plugs, cleaned the Throttle body & checked the Throttle position switch. then Put it all together & Now i have a car that is slow to fire up, but when it does start i have a steady idle and it is smooth & no missing when i accelerate (Not in gear)...

Now i jump in and take it for a test drive, I cruse down a 200 yard hill in first.... I go thru first gear when i hit this level road & all is fine with the world... then i drop it into second & i get this terrible hesitation & miss. As the car starts to crawl to a stop & i get off the road. The car comes back down to Idle & is running rough as ever, missing hesitating & the Idle keeps dropping, it sounds like it is running on two cylinders...

So i turn off the car & look to see if something was off & the Coil felt cold, so that wasn't overheating... I check the plug wires & they are tight... So while i grab my cell phone & about to call a wrecker... I tried to start the car again & to my surprise It fired up! So i quickly slammed the hood, jumped in and cruised up that steep hill (about 200 yards straight up & pulled back into my driveway) all in first gear.

is it the module (whats the name) in the distributor that is bad because of the arcing of the old Dizzy cap? how do you test to see if it is? or is it something else?

Sorry for the long rant But i thought i would be as specific as possible. Any & all advise would be greatly appreciated!
