Flat Spots
« on: 15 February 2007, 15:32:35 »
My engine has developed a couple of flat spots between tickover and just over 4000 revs when pulling hard.No EML light on or any other indicators to problem.Its not terrible but getting more noticable. Any ideas?

I didn't notice flat spots on mine, but this made it go a lot better.  If you need a one way valve PM me with your address and i'll chuck a spare one in the post to you FOC.

The other test to try with a warm engine is to wack the throttle wide open at idle speed and see if the rear multiram valve opens (very quick though so watch carefully) and then if you rev it hard to 4500 ish you should see the front multiram move.
