Hi all.

I started to make the car a little les noisy so removed the HKS SSQV and today the Tanabe exhaust was swapped over.

When I removed the HKS dumpvalve about a week or so ago, after I fitted the original plastic one back on, the car has been hesitating alot.

Mainly notice it when you change gear, the revs drop then as you go to accelerate, it holds back, judders a bit, then starts to pick up.

Have I done something obvious?

Ive just bought some new oil and filter, air filter and fuel filter to give it a service, but I didnt want to go changing things before I know what the problem is.

anyone got any idea's?

cheers
Tony
