Low rpm in park
Yesterday, I cleaned the MAF and the throttle body then cleaned the whole engine with simple green and turtle wax tire foam. Now my truck runs like a stripped ass ape but when I stop and put it in park, my rpm drops to 600, before it was 900 in park. Is this normal for the rpm to drop to 600? Thanks Mike
