Reversed idle speeds
My buddy is driving his truck again and it’s been running great with the new cam. The only odd thing is that at cold start the truck will idle at 800rpm, but after it warms up it idles at 1100rpm. It’s a 93 F150 with a 302, we installed a comp cam and removed all the smog equipment. My first thought was vacuum leak.
