M42 Vehicle Speed Sensor/ Timing off/ Bad Idle?

[lolcantturn]

what about fuel pump? checked pressure?

Nope I have not. I figured my problem either lies in the fuel pump or the timing is off. I will get on testing that fuel pump though.

Chances of it being the fuel pump though?? I figured its not since the car doesn't break up at higher RPM's.

hmmmm it cant really be timing... The car drove fine and then all the sudden this happened timing is unlikely.

It very well could be a weak pump. Weird things happen when they start to fail. How many miles are on the current pump?

Probably infinity miles. Just kidding, but a lot. I'm gonna guess 80k-100k. Doesn't whine or anything. I've put 21,000 miles on this car, the idle has always been erratic like it is now. The pump would have gotten gradually weaker I feel.

dont throw parts at it. Get a fuel pressure tester and see where you are at. report back after. its something stupid. eliminate easy things first.

check your harmonic balancer

just found this from digging for solutions to my current problem and it sounds very similar if not identical. was this ever resolved?
