Still having problems with my 1983 4/4 it has a cvh engine, and to date I have cleaned out the fuel filter, cleaned the breather pipes, and felt the vacuum pipes (they compress and seem to be supple, I have replaced the distributer cap, rotor arm, ignition amplifier, coil (these are Intermotor brand) and checked the leads also the plugs are a nice light brown colour and the car runs OK for about 18 miles then it looses power, and starts to chug I have to rev it at traffic light sand when I got home it cut out and wold not start for about 10 minutes. I would be grateful for any suggestions, does anybody know of a garage in Liverpool who could help?, I would go to Lifes only they are very busy.
Does it miss fire when it starts loosing power? Sound like possible fuel issue or condenser braking down as it gets hot. Have seen this caused by burnt valve not seating properly went it gets hot hence loss of power. Does it burn oil, look at exhaust and see if black or it whitish grey, if sooty the get a compression test on all cylinders, if one is low could be valve or leaking gasket between 2 cylinders that gets worse as engine heats up.
Hope you resolve easily.
