I guess a short introduction followed with my tech question. I am in absolutely no way a truck guy. I actually hated them up until recently when I purchased my Ranger. I'm 18 and this is my first time wrenching on a vehicle.

Before the Ranger, I drove a 2g Eclipse, that was my first car and will always be my favorite. Sadly do to money situations, I could afford it anymore. Any who, on to the tech question.

I bought a 96 Ranger 2.3 2wd 5speed for $750. Everything checked out great. Literally not even 24 hours after I had it the slave cylinder went out. So I dropped the tranny and replaced it. Then come to find out, I have a waterfall leak in my thermostat housing. I just got that replaced tonight aside from this guy trying to help and ruining my gasket so it all has to come back out.

Earlier this morning when I turned the truck on, I could tell it was idling super high. I plugged a tach into it and its idle is at 2500.

I have no idea what could be causing this. I read on here that the throttle body could be getting stuck open but I looked at it and it seemed to be opening and closing just fine. Also maybe carbon build up?

Any help is greatly appreciated.

Clean the idle air controller also unplug it to see if the idle changes.

I also read about the idle air controller. A lot of today day was spent cleaning little things up and getting the new housing in. I'll do that tomorrow. Thanks

Update: I unplugged the idle air controller and after that, my idle was around 1100 but when I would start moving, the motor would start to bog down and have a hard time staying on. I'm having a hard time get the actual controller off. This truck was very poorly maintained.
