SOURCE: car loses power when going

The first thing you need to check is fuel pressure. If you don't have a fuel pressure gauge you can buy one from a tool supplier, but the gauge may costs more than the diagnosis from a shop.
Another thing you may want to check is you catalytic convertor to make sure that it is not plugged.

Find your firewall electrical junction block (where all the wires enter the cabin on the passenger side) and with a zip tie pull up the wire bundle so it does not ride on the upper tie rods and, fasten the zip tie to anything that is solid in the engine compartment and, let me know what happens

when u press the gas pedal to go this opens the throttle valve, the idle speed of your engine is computer controlled, this is done by the ISC (idle speed control) airbypass valve, these parts get full of gunk and then get a stalling problem at or near idle, clean them by doing the following, if u don't understand the instructions seek help from your friend.
, 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 have a 1990 dodge dakota 3.9 liter v6...idles rough and stalls out at stopping...i have changed cap rotor plugs and wires...and also the throttle positioning sensor...no change..any ideas would be...


Do the service below.

Engine stalling and rough run issue at low speeds

This problem 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.

It is worth checking if you are having an ignition problem. First check whether you have spark. Remove one of the spark plug wires and look to see if it is sparking when you turn the starter. Check the distributor wiring and harness. Check the distributor rotor. Also you should check the ignition coil.

Have your throttle body cleaned and if this does not solve it have the cars IAC idle air control checked to insure it is working this should take care of your concern.
