2003 4.0 RPM drop when shifting to park
So everything runs fine while driving, RPM's don't drop below 750 when I stop... until I drop it into park or neutral ( with the AC off ). Then it drops to around 250 or less. 50/50 if it stalls out. With the AC on it only drops to around 500 and then comes back up to around 600 to 650.
Never had a truck drop RPM with no load. I'm thinking somebody changed the computer or the program in it. I purchased the truck used a few months back.
