If it's pulsing the revs - jumping up a little over idle like you're just touching the throttle - that could be a bad injector not spraying properly and giving you uneven running. Sometimes the revs can jump as high as 1500+rpm, and it's worst when very cold or very hot. Another symptom if it's that would be trouble starting it in the cold, no matter how many times you run the glow plugs.

To bleed the cooling system of a diesel 1500 CC Peugeot 106, start by ensuring the engine is cool. Locate the coolant reservoir and remove the cap. Fill the reservoir with a mixture of distilled water and coolant until it reaches the maximum level. Start the engine and let it run until it reaches operating temperature, then rev the engine a few times to help release any trapped air. Finally, recheck the coolant level and top up if necessary before replacing the cap securely.
