Clean throttle body, change the fuel filter, any codes? you could do some adjustment that last thing. It is set screw at the throttle body. You can put DW40 on cable to throttle body.
Check that the throttle cable is not too tight

SOURCE: dodge ram 1500 engine rpms surge at freeway speed
those sensors could cause the issue, clean the MAF 1st, also clean the idle system using the following procedure, the IAC can cause cruise surge. I use this to cure these problems all the time.
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve (IAC) and throttle valve, they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
I have 1999 Dodge 1500 gas motor. It has a high idle and when I let off the gas it stalls out. The truck also has a engine light on. What do I do??????
