Quick Help Peugeot 106 problem

[allstaruk]

I\'ve worked out which pin it is and after performing the ecu fault code test it says that there are no faults.

After changing the plugs and generally cleaning everything up it starts easily and runs quite smoothly after letting it warm up, it revs to about 4k but seems to stop there, its not taxed so I can\'t take it out on the rd and test drive it.  

Does this engine have a rev limiter when there is no load on the engine?

Any suggestions are welcome.
