i have a 90 integra gs (all stock no mods). i was driving and it all of the sudden just died. the enigne didnt blow up and it didnt make any funny noise before cutting out. i tried to start it up but it wont completely turn over. i tried the battery, spark plug wires, checked ecu (no flash codes), i even put some gas thinking i was out and the fuel gauge broke. i checked the dizzy and the cap was very dusty inside, i then noticed the rotor was damaged the metal mount where the set screw mounts to the rotor came loose. my last guess id the dizzy but how do you know if that the problem...? i noticed for tha past wekk my car has been slugish and idle would kinda jump up and down (+/- 150 rpms). any help would be greatly appreciated.

 

i already swapped it(rotor and set screw) , btw when i turn it over it sounds like a tennis ball is shooting out the exhaust.
