Re: Seville 03 shaking problems after tune-up.

Hey,

I didn't have time to go through the problem, thanks a lot for your reply.

My problem persists of a intermittent rough idle

I ended up changing the boots, but the car still idles rough from time to time.

I noticed there is a sound of an air leak coming from the engine. It seems to come from the area around the vacuum on the rear cam cover and the A.I.R valve area. When the engine is running, and I disconnect the vacuum hose on the rear cam cover, and block it with my finger (the hose) the air leaking sound goes away, but the hose seems fine. The car also consumes a lot of fuel (10 mpg mostly city), I think the problem is related...

What can the problem be???
Is it possible that it is the A.I.R valve?

Thanks a lot.
