I have this problem that just showed up all of the sudden.
For those of you that don't know my truck, it's a '93 s10 4x4 6cly auto.
I drove to and from work on Tuesday with no problems. I came home for about 15 minutes, went to get my plate sticker renewed and then went home. I cooked dinner, then started up my truck to bring my girlfriend dinner at work. As soon as I started up, I noticed something off. When I accelerated, there was a terrible shaking, and it took a long time pick up speed. I had come home on a road that has these speed humps, so maybe something got bounced around when I went over one?
It is not as bad when the truck is warmer, but there is still an obvious issue. It only happens when I hit the gas and it is there slightly at idle. When I coast it is not there at all.
Some history: I just replaced my resignator pipe and fuel filter last week. I still haven't replaced my engine manifolds ($), so they have some cracks in them. There are no check engine lights coming on at all, which makes me think it is NOT a sensor issue. However, it has been cold outside, so maybe because of the cracks in the manifolds, the cold air could be screwing up the sensors. I haven't driven the truck since. I have started it up once since Tuesday and it was still shaky on idle. I haven't tried to get any codes since there isn't a light coming on anyway, so it probably wouldn't have one anyway.
This is what I think COULD be wrong:
Like I said above, maybe some sensor going all squirrelly because of the cold air.
Throttle body might need a good cleaning. I haven't checked it yet because it's been either cold as hell or freezing rain outside.
I DON'T think it is fuel related, and I certainly don't think it has anything to do with the fuel filter being replaced.
Any input or something I might be missing?

Sounds like a timing issue to me, but who knows.
I would ckeck your wires to make sure you didn't melt one to the manifold, and check for heat cracks. also check that they are all tight at the cap and plugs.
All that I can think of at the moment.
Good luck
Wait till its warmer outside though, its freakin freezin here and all roads are closed up again.
