Check the catalytic convertor...if the isn't much exhaust coming from the tailpipe when you rev it up, chances are the convertor is plugged.

SOURCE: misses during acceleration , rough

Go get the codes ran at auto zone or advance auto parts they will do it for free. If the codes come up as a cylinder miss-fire then it is most likely a coil (being a ford). Write down which cylinder it is. I wouldn't replace any of the spark plugs , useless you have more than 100,000 miles. If you have to replace the spark plugs use BOSH double plautim or better. The cylinder placing is ( as your are looking at the front of the truck) passenger side front to back 1-2-3-4 driving side front to back 5-6-7-8. If you never seen a coil buy one so you know what you are looking for. The coil is held in by a 7mm bolt. Take the bolt out and replace the coil. Problem Solved. Estimated time 20 Mins with 60 dollars per coil.

SOURCE: loss of acceleration and power on 2003 dodge ram 1500

The acceleration may be an issue with the clutch or with engine.  If it is a manual tranny, you may have a worn out clutch.  For automatic, you may need to have the solenoid cleaned or have the tranny serviced
Other issue could be on the engine, check first the fuel filter especially if you encounter loss of power when running.

SOURCE: 1993 Lexus Ls400 loss of power at 2500-3000rpm

Check your MAF and MAP sensor. The first 80% of your throttle signal from the TPS works with the O2 sensor to try to keep the air fuel ratio to 14.7 to 1 with the ECM controlling the fuel injector spray time and timing the ignition. After the 80% to WOT the ECM puts the O2 sensor in to an open loop and takes the Reading form the MAF and MAP sensor to run the engine richer so there will not be any Detonation to the engine and burning holes in the valves for running too lean. That is why it always feel like you get a little more when you ease off on the gas peddle from WOT. Recap check the TPS, MAF,and MAP sensor and wires to those sensors, if you can get the car scanned that would be great and you may find out which sensor may have gone bad, the other thing to is the fuel pressure regulator may be going bad and at WOT the pressure may be to high causing it to run to rich causing the loss of power. Good luck and hope this helps.

SOURCE: check engine light p0411 code what must i do

this has to do with your secondary air injection incorrect flow. start looking for a vacuum leak especially around the air duct from the mass air flow sensor to the throttle body.

Wish I had an answer - sounds very much like a problem I am having with my '92 LS400. I have a parts car, and have changed out the ECM, fuel pump, injectors, fuel pilter, fuel pressure regulator, ran the can with exhaust unbolted (check for clogged CATs, checked out my timing belt for slippage amoung other things, and nothing works. I have no check engine light on. Do you?

2001 Ford F650 with 7.2 Cat deisel acceleration problem
Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.

It sounds like a fuel delivery issue so it could be many things such as low fuel pressure from the pump,clogged or partially pluged fuel filter, a malfunctioning throttle posisitioning sensor (if you have a check engine light on) or if its turbo it could be turbo lag etc.
