MY 1992 Proton Saga lacks pick up at mid-range ( usually at
around 40 km/h).
Is this a compression problem ?
Answer : Around 40 km/h, in what gear and at what rpm
When one talks about mid-range, we usually mean middle of the
operating range of the engine rpm, i.e. if the maximum rpm is
6,000, then the mid-range would be about 3,000.
You could be trying to get the engine to pull at 40 km/h in
5th gear, and this would be difficult as the engine revs would
be very low and may be pulling very low torque.
