Idle issue
Hello. New member.
2004 Dakota 4.7 auto trans 120k miles
Here's the breakdown.
When I start it cold the idle will jump up to around 2500k rpm. Takes about 30 seconds to settle down.
When I put into gear I have to wait a couple seconds for it to shift otherwise I get a hard shift.
The idle will jump around while cruising like it's shifting in and out of overdrive. Sometimes I'll get a hard shift. Trans fluid looks ok but could benefit from a flush.
Worse when cold. Still happens when warm.
Things I'm leaning towards: throttle body dirty. Spark plugs. IAC. TPS. MAP.
What should I start with. I don't want to just throw parts at it and I'm limited on cash.

Today I started it up. When I tapped on the TPS there was no change in idle. When I tapped on the connector there was a small change in idle.
So I took the sensor out and cleaned the connectors. I also cleaned out the throttle body with brake clean. I know carb clean would have been better but that's what I had to work with.
Took a test drive to the store and so far it seems to be acting better. Gonna drive it over the weekend and decide if I need to replace any sensors. I'm just poor at the moment and don't want to throw extra money at it at the moment.
