"YoYo"/Air Bypass Valve in Chester

[mikydisco]

Hi All,

I’ve been having some ‘yoyo’ at 2-3000 rpms when driving my 2004 r53. Had a good trawl/research around the forum and i’m convinced it’s the Air Intake Bypass Valve. The car runs fine flat out and at low speeds but it’s the ‘middle’ driving when this little beastie appears.

I’d like to get this sorted out ASAP but could do with any info on specialists in the Chester/North Wales/Wirral area who have a good rep for problem solving and doing a solid job.
Thanks everyone.
