Question about 1988 Dodge Dakota
I replaced the fuel filter , plugs and wires. new TPS sensor. but still idles rough and dies at every stop. could it be timing???
Hi Mosso, Yes it definitely could be. Reset it with a stroboscopic timing light. It could also be leaking vacuum hoses so check them all for tightness of fit and make sure there are not any which are damaged. Regards John

Change/thoroughly clean the idle control solenoid. It may be sticking and causing rough idling.
Cleaning it is unlikely to be more than a short-term solution.

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), 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 think you have ruled out the engine with all the parts you have replace. The transmission torque convertor is in lock up mode all the time. The engine is having to hard of a time to stay at the normal idle. The over drive clutches and soleniod are most likely damaged in the transmission.
I think you should take the vehicle to a trasnmission shop , The can check the torque convetror soleniods and pressure control soleniod.
The oil light coming on bothers me. I know you have the rebuilt engine in the vehicle but I think the oil pump in the engine is starting to go out or could be weak. The lower bearings connected to the crank shaft might be starting to leak. Have the oil pressure checked .

Once you have the new PCV valve locate the old one on your engine. It will sit on the middle of one of your valve covers (most likely passenger side) and will have a line that connects to the top of the valve. Simply pull the old one out and put the new one in snapping that line on the new one. Should only take about a minute to do. Hope this helps, let me know if it does.
