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.

SOURCE: it starts fine, runs 20-30 seconds, runs rough,

check the actual fuel line. Also is it fuel injection or carberator

SOURCE: i have a 1987 dodge ram pickup with a 318 engine

try a new accelerator pump in the carb,a reiuld may be the best bet.Check for vacum leaks first.

A carburetor type engine has the pump on the engine near the front on the side--trace the fuel line down. Fuel injected engines have the pump located in the fuel tank.
