So I pulled off a throttle body from a 4.0L '96 cherokee at a junkyard. I tried to swap it onto my 2.5L and I've ran into some problems.
There is a little nozzle on the east side that looks like a vacuum line. I don't have a hose for that. So I plugged it.
I replaced the sensors with the sensors from my 2.5L throttle body.
When I start the engine, it revs up over 4000 so I kill it. I don't want to let it run. It's not good to run it over 4000 with the engine cold.
Thank you for any and all help.
