Hey there Thought this might have been the solution to my cars sluggish feel. I pulled out the solenoid removed both pipes and sprayed WD40 through it so WD40 was goin in one pipe and coming out the other, dont know if that was the right way to do it?! I didnt spray any WD40 down the hoses that connect to the solenoid, should I have? anyway dont think it made a noticable difference, hard to tell cos it was lightly raining which caused traction issues. Earlier that day I had changed the oil and put in new spark plugs which hasnt improved the feel of the car. Any ideas what I might try to get back the power?? Its a 04 BA XR6T with 61km stock standard with a new KN panel filter. Having a look on here I guess cleaning the throttle body would help and maybe the exhaust manifold studs may need tightening?? any help would be appreciated! Cheers
