1968 Plymouth fury 440
Hey guys, I've been chasing down some crazy drivabilty symptoms for the last few months. This summer I changed all the plugs, installed a new fuel pump, and fuel pump pushrod, that solved all the fuel starvation, and poor running issues. a few months ago I was driving my car, and it started running terrible... No power, missing just rough all together. I swapped the fuel filter, and that helped some. I did a test, and found out my distributor vacuum advance was blown. long story short I swapped that out, and the car ran perfect. I go to drive it the next day and it's back to running erratic. idle is terrible, has ok power, but it's just lazy. I changed all the plug wires, and it seemed ok. but I go to take it out this morning, and it won't run right at all. There has to be something crazy simple that I'm missing here. when the car is in neutral it runs ok, but you can here the miss. when you put it in gear it surges, and the ampmeter dips way down.
