Question about 1987 Dodge D150
Have 1988 Dodge Ram D150 318ci when engine is cold it surges and when warm runs just fine. Distributor, wires, plugs, selonoid have been replaced and still surges when cold
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.

Porbably not getting enough gas or dirty. My 88 dodge caravan did that too until I put a cheap fuel-injector cleaner in with the gas, and started giving it more gas even in lower gears driving around town. Worth a try...
