Could it have been Oliver Gunnell who typed:
||| Is this an automatic?
||| full throttle switch working?
||| I have seen some screens inside of the large intake manifold rubber
||| boot turned upside down?
||| exhaust restriction like a partially clogged cat. conv?
||| possibly wrong fuel pump relay causing the pump to shut down at a
||| certain rpm??
||| restriction in the air intake for the air filter box?
||| oil level too full?
||| incorrect adjustment of the accelerator cable?
||| bad distributor cap, rotor, plug wires or ign coil?
||| bad knock sensor?
||| to name a few reasons or possible causes off the top of my head.
|| This is a manual, what I dont understand is in neutral it free revs
|| and sounds really smooth I can hit the red line with the pedal to
|| the floor
|| But why do things change under load?, does the above rule out cable
|| and throttle problems, under point towards poor fueling or air?
free revving, i.e. not under load needs very little power (not a good idea
As soon as you put the engine under load, the spark has to work harder, you
need more fuel, the advance and retard mechanism whether mechanical or
electronic changes the timing, the amount of air drawn through the airfilter
increases etc etc.
So any one (or more) of the suggestions already given.
