Hello, I am new to Ih8mud but I have searched for my idle issue and have not found a similar problem. When I start my 94 up, it runs great with the idle around 1000. After the engine gets warm and the “choke” isn’t needed anymore, it wants to idle around 400. I looked at every hose and checked every clamp as that seems to be the answer for other idle issues. My mechanic sprayed starting fluid at every hose connection to see if the engine rpm would increase but that didn’t work either. He then thought since I bought it two weeks ago on the west coast that our elevation of 7000 feet might be an issue so he advanced the timing some. That worked for about 10 minutes driving (the idle rpm was around 650) but then after 10 minutes it went back to 400.
Thank you in advance for any advise!
