revs high

can you help my rover75v.6 revs seem to be high can this be ajusted

How do you mean?
Is this when you first start the engine or after you have been driving it?

Some V6 owners have issues (me inculded) with the throttle sticking some times, I have found that cleaning all the throttle assembly and fitting a catch tank has 'fixed' this issue.

You could find the idle control valve which is located on top of the Throttle Body needs cleaning?

Do you have a catch tank fitted on the breather pipes?

Does it do it all the time or intermittently?

Somewhere around the 800 - 1000 mark I would have said.

What are you seeing?

If your good with taking things apart then I'd suggest removing the airbox from the throttle body and giving it a real good clean out with some carb cleaner.

You might see oil in the intake which is due to the breather pipes from the engine, also remove the idle control valve which is the square looking box located on top of the throttle body and give that a clean.

Sound like the butterfly in the throttle body might not be closing properly due to being dirty perhaps...

Worth cleaning out to see if it helps, also check the throttle cable isn't snagged on anything or the pedal is caught on the carpet/mat.

You could try removing the Throttle Cable from the Throttle body and slacken off the adjuster a few threads.If this makes a difference you might have to adjust it a few times to get it right.Type in "Throttle Cable Adjustment"in the Search box of The General Forum page and you'll find a step by step guide by Mr Edd.

tick over should be 750 revs per min+/- 50 revs.
