Question about 1994 Dodge Dakota Club Cab
Drove the truck a few miles no problems.
Shut it down and went to store. I come out 3 minutes later and restart the truck (barely)...it idles rough, missing, if you give it any gas it bogs right out and will backfire (through the intake it seems). Idle seems to get better after it warms up more, but it just bogs if you give it throttle. if you feather it just a bit, you can rev it up quite a bit in neutral, but add any more throttle and it dies.
this problem came out of nowhere. I put 700 km's on it a day prior.
spark seems good and fuel delivery seems ok too. its was cylinder 2 and 4 that don't seem to be running initially (front two on passenger side bank)
If you give it gas and it almost dies, and then you let off, it will stumble for a bit, during which you can here a sucking (like a straw) sound through the throttle body (with the intake cover/filter off). then when it starts idling better you don't hear it.
Also, no engine codes. checked spark plug caps and leads, all seem ok.
Try a vacuum gauge and see if it reads what it suppose to you might have a vacuum leak

Check the distributor shaft. They have a history of developing finite cracks that causes the condition your describing. Let me know if I can help you with any other info.

Engine stalling and rough run
issue at low speeds
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control. If this doesn't improve the problem you have mechanical problems in the engine like a low cylinder die to worn rings or leaking valve seats.

Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue 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
