Blew the vacuum line off the MAP sensor the other day driving home and after finding and fixing it I decided I'd address my noisy rockers. I set all the valve lash to 0 then 1/2 turn with the motor running and it sounded better. I then drove the truck and idle drops down lower now when in gear and knocks.
Runs like a top in park. Is the MAP sensor still sorting itself out? Why'd my RPM change in gear now? Have I got a different vacuum leak?
