Zjones1994 So tonight after cleaning the throttle, iac, and tps i had a code come up after. Took to auto zone and had 3 codes
PO505
Iac circuit condition higher/lower than expected.
P1281
Engine cold for too long
PO123
Throttle positioning sensor.
The iac one is the only one that has multiple things that could cause it. Im assuming replacing the iac but it also says vacuum leak. How do i check that?

gomezaddams I had the same problem in my mustang. After going through everything else replaced the throttle position sensor even though it checked out fine. No problems since. Do clean the iac and mass air flow sensors first though,just to see.

Sccafire Check all you vacuum hoses. Make sure they are all hooked up properly and do not have cracks or holes in them.

Zjones1994 I just took it for a drive after checking the throttle body and its clean as can be. Air filter is good. As far as i can tell the throttle cable isnt hanging up. I did notice it only happens when im in neutral, or with clutch engaged, and moving. Once i come to a complete stop they drop back down

rpms raise when clutch pressed

I just changed my thermostat and long story short my jeep was drivin by my dad for about 5 minutes after it overheated. That's not the problem, now everything is worked out, though i need to change the t-stat again , but now whenever i drive il press the clutch in to shift or come to a stop the rpms go to somewhere around 1500-2000. It only does it after being driven. Idle is at about 750 though it does seem a little rough. Anyone have an idea of whats going on?
