I'm not up on working on cars much but i just got a 01 Dakota with the 3.9.
It takes usually 2 turns of the key to start,runs just slightly rough liker
i can feel a slight shake when stopped at a light,like the old distributor
engines used to give when a little out of time. I was backing it up moving
my boat yesterday and it idled a little low and stalled.
To me I would think the fuel injectors are clogged or the plugs need
changed.Would either of these things help what I described above? Its got
55k miles on it.Thanks!
Sounds more to me like a dirty fuel or air filter. Broken vacuum lines
generally will turn on your "check engine" light. It never hurts to change
the plugs. While you're at it; run the truck in the dark and look for arcing
from the plug wires and make sure they're on tight. You might want to check
for carbon build up or a crack in the distributor cap.
I dont think the 3.9 has a distributor does it? I looked and all the wires
seem to go to individual ignition coils.
The fuel filter might be a good idea though,i will take a look at it. I am
thinking fuel related.
No it don't have one. We have a pickup that is placed on the right side just
behind the head on the bellhousing. This is your pickup for crank position
for firing the plugs. Myself I had to change mine a year ago on my 2001
dakota. Stumbled, misfiring down the highway, scare the sh*t out me..lol,
They do fail.. but I got a code for the pickup problem. You have no
statement of any codes is this correct. you should see if you can do a
reading of the fuel rail for proper pressure. Like you said could be filter
Or a long shot it could be the throttle body.. The air-bypass bleeder on it
could be sticking or dirty, That controls the idle circuit.
