Dodge Dakota Engine and Underhood Questions



  • Dusty,

    Thank you for your reply. The engine I have is the 6 cyclinder. I installed a flush kit and that fixed the problem. I talked to a person at a local auto parts store and he said I need to remove the radiator cap and let the engine run. This lets any air bubbles out.

    Thanks again,

  • i have a 1992 dodge dakota 4x4 with the v8 it will not run properly sometimes it will start right up and idles great but when i drive a little it dies then when i try to start it back up it doesnt always die though sometimes it does but it just wont take any gas it has also done this while driving ill be riding along at about 25 mph then it just stops accepting gas im pushing the pedal to the floor but she will not respond i have to coast over and manually turn it off and restart it a few times till it will accept the gas again i obtained this truck as is so i do not know what led up to the problems someone please know th3e answer to this cause i can not afford a diagnostic
  • my dakota loses power to the coil when i give it gas.. i have replaced the fuel pump, coil, cam plate under the distributor cap and the oil pressur sending unit.. my truck will idle all day long, i can wiggle wires, vacumn hoses and what ever, and it will stay running, but as soon as i idle up the engine, it dies.... i have a tester on the coil, and it loses fire to it... after i try starting it a few times, sometimes more, it will start back up, but can only idle.. im running out of ideas and money....Engine is a 6 cyl, 3.9 PLEASE HELP !!! Mike
  • today i changed the crank position sensor 2/25/07 -------it still wont run with the motor at high R.P.M.s.... i was told if the check engine light isnt on, then it wont show a code....
  • Hi guys, its been awhile, i have had a lot going on. Anyways, I have a 01 QC 4.7 auto 4x4 with 77k miles. I was going to change spark plugs again with the stock champions but was wondering if any great successes with a longer lasting platinum type????
    Also, I was going to change my trany fluid. Done this before on other trucks, but I understand my auto trans has a spin on filter inside. Any special tools needed or tricks to know?? Any help and comments appreciated.

    A lot of folks are running Bosch Platinum +4 (#4418)in the 4.7L semi-hemi engine.

    As for your xmission - I special-ordered he manual xmission myself. I do know that if you do not use the proper ATF+4 (synthetic) fluid in the automatic, you would be asking for troubles.
  • i have a 2001 dodge dakota quad 4.7 im putting new universal o2 sensors in and the wires dont match the old wires are blue, white and 2 blacks new wires are black, grey and 2 whites the sensor is a sng # sn4-102 what do i do?

    the best plugs to run beleive it or not are the cheapest,they are also a cooler running plug. Auto Lite 3923, you can pick them up at wal-mart for 10 bucks for all 8. Plugs with plat. tips will detonate and cause problems.

    if the connector will plug in then you should be good to go if not you might want to return it because itis probably the wrong one.

    In this model year there are a number of things that could cause this problem. I have seen aftermarket tune up parts, such as distributor cap, rotor, and spark plug wires cause similar problems. Bad or worn spark plugs can also be a cause. I would recommend using only Mopar ignition and tune-up parts.

    A bad PCV valve can also cause this, especially in the winter time when there's higher levels of moisture in the crankcase. The water freezes the PCV plunger as vacuum pulls air through the crankcase, causes reduced air flow (essentially closing the throttle) and stalls the engine. Clogged or partially clogged PCV valve hoses can do the same thing.

    More serious things could be a bad crankshaft position sensor, a bad intake manifold gasket, or a defective catalytic converter, clogged fuel filter, bad fuel pump.

    I'd start with the ignition components and closely inspect things. A vehicle that old is bound to have cracked rubber vacuum hoses. Check them all.

    Did you seem to take a dip in gas mileage suddenly?

  • dustykdustyk Posts: 2,931
    I, too, have used the Bosch Platinum+4s my 4.7. They've given me no problems, but I've changed them out at 45,000.

    If you have the 4.7 engine the automatic transmission is the 545RFE. This transmission uses two (2) filters. The primary filter is attached by a screw typical of older Mopar transmissions. Be careful of seal when installing the new filter. The second, oil cooler return filter is installed using a small oil filter wrench.

    CAUTION: Only use Mopar ATF+4 (MS-9602)automatic transmission fluid, Chrysler part number 5013457AA. Do not use ATF+3 or any other type of fluid.
    Best regards,

    Okay, can you be more specific about the loss of spark as the engine RPM is raised? Have you checked the polarity of the coil?

    Just because the check engine lamp is not illuminated, doesn't mean that there is no code stored.

    Hi Dusty, Yes I am aware of the ATF+4 and have used that before for top off. So am I to understand that I wiil see a flat type of screen filter with a tube for one filter (what i'm used to) and also a second motor oil type screw on filter as well. I do not have an optional trans cooler.

    i found the problem with my 94 dodge dakota (finally) it was the wire going to the transmission, it got a bare spot in it some how, and when i gave the motor some gas, it must of caused it to ground out and send the computer a message to shut down for awhile... thanks for any help.. muntster

    I have a 1997 2wd dakota 5 speed with a 2.5 4 cylinder engine. th eidle out of nowhere, is high , extreme loss of fuel mileage, and a check engine light on saying misfire cylinder 1, and all the cylinders have good compression, clear that code, and the next code is somthing about high idle.. can anyone help..
  • bthevbthev Posts: 2
    Yes the gas mileage suddenly dipped. It was right after I had an oil change to a high mileage oil and a belt replacement to bypass the failing compressor for the A/C.
    Thanks for the reply.
