Hey all, I recently purchased an 88 for a project vehicle that has the high output motor with renix components on it. In park it wants to idle right around 1500 rpm. When I put it in gear it drops to just below 1000. I was wondering if this is normal and if its not is there anyway to go about dropping the idle speed. I am new to the jeep world so any help would be awesome

 

Vacuum leak

 

thanks Ill check the lines, is there anything else that could cause it?
