I found a messed up intake gasket. Replaced intake gasket. Also found one of the intake vacuum hoses under the manifold had come loose. It seems to vary on the fuel regulator pressure I have read anywhere between 35psi and 48psi.But you think about48 psi on an 1989? Anyway it still seems to miss at about 5500rpm. Could it be from the hole in the intake boot getting the throttle body dirty? It also fuel fouled the plugs I cleaned um but I think news are in order
