Post by: Cambo44 on 06 May 2014, 19:45

Hi anyone got any ideas,

Wen I start my car it goes to 1000 revs which is normal however it then starts increasing without me putting my foot on the accelerator to 2000 then drops back down again ?

Please help

Thank you all in advance

sounds like you could have a faulty pcv valve. one way to check is the oil filler cap will be a b!tch to get off while the engine is running.

Thanks for responding, what will I be looking for when I get the oil filler cap off?

Many thanks

When the engine is idle and warm, take the cap off very briefly. If the engine goes to stall your PCV valve is working. If it carries on at idle with little or no change in revs then the PCV will need replacing with the latest version.
