feels like it wants to stall

[polcat1p]

my 01 sport trac feels like it wants to stall. it doesnt stall and the rpms dont change, but the engine just doesnt seem to run as smooth as my o2 ranger with the same 4.0 motor. the prev. owner put new plugs and wires about 5000 miles ago, and had the injectors cleaned. i have also changed the fuel filter,air filter, and seafoamed it. is this normal? my miles are high(159,000)
thanks

Check this PCV elbow IF you have a Job2, and haven't already.
If not, clean your IAC valve, throttle body, and MAF sensor using their specific cleaners. (CRC Industries)
