Truck shakes in gear and no power
I have a 1983 f150 inline 6 with an automatic. It shakes the the truck when I put it in gear it smoothes out a little but it won't accelerate over a crawl. Fuel pump and filter have been replaced. The plugs and wires have also been replaced. The timing may be off. If anyone has any ideas

If you pop the distributor cap off then turn the engine over (by hand) in the direction it runs - clockwise viewed from the front of the truck - until you have No. 1 piston at top dead center on the compression stroke - NOT the exhaust stroke. While doing this, watch to see the direction that the distributor rotor turns.
Once you have TDC on the compression stroke of No.1 cyl, the rotor will be pointing to the cap position of the wire for the No.1 cylinder spark plug, so don't turn the motor any further.
Good idea to mark this wire position on the cap to eliminate confusion later; you can now put the cap back on the distributor.
Now carefully follow the wires, in turn, from the cap (in the direction that the rotor turned) & see if they lead to the cylinder corresponding with the engine firing order.
So, with the firing order being 1-5-3-6-2-4, the wire at the No.1 position on the cap (that you found) goes to the No.1 cylinder - that's the front one.
The next wire from the cap, going in direction the rotor turns, goes to No.5 cylinder & so on.
If you go carefully step by step you can find any misplaced wires. If one is wrong, at least two will be.
When you think you have it all corrected, I would start at the No.1 position on the cap & check all the wires once more.
Good luck

Checked the plug wires and they are hooked up correct and I think I got the vacuum lines figured out. I increased the idle some. It still shakes when I put it in gear but not as bad. It also feels like it is ******* out and wont accelerate in gear. It won't drive over 5 or 10 mph and feels strained.
