Runs great when ice cold and above 3000 rpm. The miss is coming sooner and sooner. I guess when it doesn't run at all, it'll be easier to find.
Help!

50psi all the time?
FSM says that there should be changes in static pressure, dynamic, and in response to vacuum change... UP to 4 psi drop, maybe more, IIRC here.
ed.: Yep - up to 10 psi less.
