fault in plastic pedal sensor
low oil

shift solenoid fault

As long as it's a manual transmission and you put it in neutral. I can't see any reason it wouldn't work.
Not sure about the automatic transmission though. I would ask the company.

Sorry old son but your clutch sounds like it has gone to the big junk yard in the sky reserved for dead clutches . When a clutch starts to slip it will continue to do so until that is all it will do . solution a new clutch is required .

its deffintly the clutch as these cars have a pull type clutch. which means that the clutch will keep going until the car wont move.

Possible clogged fuel filter, faulty ignition system (ie. plugs and wires) faulty injectors. Start with the fuel filter. Good Luck

possible issue with the clutch plates....get them replaced.

The setting for clutch are not proper hence clutch is either slipping too much or sticking too much to clutch plate causing the engine to overload for every single rev. Both will effect the efficiency of your engine's exerting power especially going up hills. Use the manufacturers specification for clutch force and adjestment of pressure plate.

Try this to find out the condition of your clutch system:
In first gear and push accelerator fully to drive upto 3500 revs and then suddenly move your foot away from accelerator. If you feels a sudden shock and your head tends to nag to windscreen with a force then clutch adjestments are not properly done (stifting force is more than recommended). Inversly clutch is not engaging fully.

When you have a problem with a slipping clutch, the engine will rev higher even with no pressure on the clutch pedal. I do not think it is a clutch.

I have the same car,,i think your automatic transmission is slipping,(check fluid),or if its a manual transmission,then your clutch is worn out.(replace)
