So I’ve been have a weird idle issue ever since Oct of 2020 and I can’t seem to figure out what the problem is. I’ve replace the TPS and MAP. I’ve also cleaned my IAC Valve several times. I also changed a bunch of fluids and replace spark plug and I’m still having the issue. When I start my Jeep it immediately starts to have a low idle and when I drive in warm places like Las Vegas the idle stays pretty consistent (about 650-750) but when I drive in colder/ higher elevations it drops. I also haven’t gotten any check engine lights (which doesn’t help). The only things I know is that steering pump squeals at high speeds and that my breaks need to be replaced.
