Huge probblem iv'e been lately..while driving, the radio will randomly cut out, and ill see the red gen light go on for a half a sec. it'll do this a couple of more time, then sometimes the radio will cut out and the light will go on for 10 sec or more, and the car will cut off...it will usually roll for about 10 sec and then then kick back on if i keep my foot on the pedal very lightly. ill hear a back fire once in a while, and sometimes, ill have to barley flick the ignition to start it back up while its rolling. its a really annoying problem, especially when your getting on the highway and it stalls while your merging. another problem that may or may not be related, is that when i start it up the starter will vibrate for 3 seconds after the car starts. sometimes it takes 2 or three tries to start it. i just recently changed the spark plugs, and im pretty sure all the gaps were spaced accordingly, but my 350 engine was from a junkyard car, and i have no documentation on what car it came from (it was done by the owner before the previous owner) the car is a 69 2 door nova that originally had a 307 but now it has a 350. im pretty sure it has a stock altenator. i just bought new streetfire wires too ill put them on today and see if that makes a dif.
