I have a 1995 Dodge Dakota 3.9L with mannual transmission and 233K miles. I'm starting to have some trouble with it when it gets cold outside. I bought this truck new and never had any troubles with it till this winter.
My truck doesn't want to idle when its cold. It runs great above 1,000 rpms and no problems on the highway when its cold. The truck just wants to dead when I push the clutch in to make a stop. It starts right back up if I'm rolling and I pop the clutch. I know there is some kind of idle sensors, that is suppose to kick in when its cold. I think under normal conditions it would kick the RPMS up to 800 if it fall below 600. Somethings it seems to work and sometimes it doesn't.
I just replaced the plugs and that didn't seem to help.
I turned the car switch on three times and came up with error code 55?
Any advise would be appreciated? Any diagrams would help if I need to replace parts
If its a throttle body, try cleaning the Idle Air Controller (IAC). This is for a carborated engine but its not much different for a throttle body http://dodgeforum.com/forum/dodge-ram-van/68174-diy-how-to-clean-the-iac.html .They get gummed up and wont thet the truck idle properly. The other thing that could be a problem is the MAP sensor. I would start by checking the IAC, its cheap (cost you a bottle of throttle body cleaner) and easy. I read somewhere you can pull the harness off the MAP and if that fixes the problem, then the sensor is bad, but who knows if that is really the problem. When you clean the IAC clean the whole throttle body just to be sure that isnt the problem. Hope that helps.

i have the same truck but with 220,000 miles on it. it dose the same thing but i have voltage spikes. im charging at around 18 volts while on the throttle and while driving it sometimes chokes real quick and then recovers. if im sitting and just holding the rpm's at around 1500 the voltage spikes from where its charging at 18 volts and the lights get brighter and dimmer with the spikes.
