I have mpefi manual and since i got the car always had a problem with the clutch, I have just ignored it or make do for a year now. The problem is that the clutch would take off right from the floor and is very tough to change into gears, sometimes I get stuck in between gears. Also going into reverse is a tough time without getting a grind from the sincroid rings. Also its the toughest clutch pedal ive used before to push the thing in, I get sore ankle sometimes in the city stopping and starting. Anyway after changing the gearbox oil (which changed nothing) we realised it is a clutch cable problem. So we opened the bonnet and tightened the cable by the nut at the end of the cable (nearly below the windscreen but under bonnet), then the gearbox will work fine, takes off about half way through release, gears change easily and so on. Then after a few weeks the gears gradually get to be a pain in the ass again and it needs a tighten, but each time the nut is going further up the cable.
I think i tightened it too much yesterday coz sometimes accelerating the revs suddenly go haywire like its slipping without getting the power.
Just wondering if this sort of problem is common, if not what is likely to be needed for me to fix the thing up.
