Passport 1994 model refuses to accelerate, moves very slowly after the first 100km of my trip
I just read a rather lengthy dissertation from some other frustrated owner with the same kind of problem. He had 2 causes: The first was low fuel pressure that a new pump fixed. The other was the harmonic balancer (on front of engine, bottom pulley of timing belt). It has a metal inner and outer ring with rubber sandwiched in between. For some reason the rubber had gotten hot and allowed the outer ring (cam timing) to move compared to the inner ring (crank timing). Once the balancer cooled down, the rubber seemed solid again. The timing mark on the outer ring should line up with the key slot on the inner ring.
