New/used 1990 H.R. Monitor issues.
Shortly after we purchased our Class A 1990 Monitor we noticed an issue. I will describe it below:
When attempting to accellerate, pedal pressed half distance to floor, the motor would whine up then bogg down to the brink of dying. This cycle would repeat even though we couldn't get above 10mph.
What we did mechanically: FULL TUNE UP - Cap n rotor, Plugs n wires, fuel filter and 2 can of seafoam... Also removed and checked catalytic(no clog) then did a fuel pressure test. Started out at 30psi, once acceleration started it dropped all the way down. Is our fuel pump bad?
