you most likely have a bad vacuum line somewhere...
look to see if your vehicle has a vacuum diagram decal under the hood showing a basic map of where the lines are supposed to run from you carburetor or throttle body to all the components..
Now take a can of caburetor cleaner and attach the red straw that come attached to the can... insert it into the nozzle this will stream focus the out put of the can to assist you in finding
vacuum leaks if there are any...
with engine idling at where a vacuum line begins spray and listen if the idle increases there is a leak the carb cleaner went in at that exact point and richened the fuel mixture which raised the idle...
spray along all lines from one end to the other & not anywhere the idle changes where ever it does there is a leak with new rubber hose replace each section on at a time that was leaking...
there are a couple of other possibilites too there are coolant temperature controlled vacuum ports threaded into the block heads and or water necks... these can be cracked and cause a ghost come and go type vacuum problem...
there are als combination vacuum/electric ones controlled by the computer at certain intervals when specific parameters are met..

It could be the O2 sensor, or a plugged air filter, or a plugged fuel filter, or water in your gas, or a short in the electrical system, or the computer is going, or a hundred other things.
If you have an Auto Zone near you they can hook up a machine and narrow things down for you for free.

TPS (Throttle Postion Sensor)
It could be effected by a/c or heater...the fan
Is it when in park, or driving...can you feel it while driving...
Does it move a couple hundred rpm or is it like 1000 rpm...
You may need a new TPS (Throttle Postion Sensor)
about $40 at your parts store...or have a mechanic charge you a couple hundred

Its probably the timing chain . Also depends on if your truck in newer and has fuel injection, or if it has a carburator. If it has carburator, then it can be a problem with the carburator too. With fuel injection you can check the distributor, make sure its properly alined (need special tool). Good luck.

Several possibilities
1. An intake manifold/plenum leak
2. (TPS)Throttle Positioning Sensor [assuming it's fuel injected]
3. (MAP) Sensor [Manifold Absolute Pressure]

There is a problem somewhere. Have the error codes checked at auto store and have then decipher the code for you and then you can get the part there or have them do it.

sound like a problem with the Gage (timing is off )or possibly a bad connection either way its some thing to get checked out
