Question about 1993 Dodge Dakota
I need to know why my dodge truck is surging while normal driving and I have replaced plugs wires and even computer and now when just normal driving surges reall bad?
Any check engine lights codes. I would check vacuum lines, intake gasket and plenum. Check your ignition coil. Throttle postion sensor maybe stuck. I would even clean the throttle body. May even be a speed sensor.

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.

did u try turning the distributor??? if u did u need to take it to a shop and have the cam sync reset with a scanner,turning the distributor on those engines DOES NOT change timing.how many miles on this truck?? over time the dist. gear weares and it can also change the cam sync,also look at the little vacuum port on the passenger side of the intake manifold and see if the rubber plug or hose is missing off of it,also does this truck consume oil?? if it does it could also be your problem,a pan on the bottom of the intake manifold leaks and that could cause yur problem also,to test for that simply put your thumbs over the holes in the valve covers with it running..if it sucks yur thumbs in, that gasket needs to be replaced and it will also cut down or stop your oil use,hope this helps
