Hi all,

I have a 1.6 1999 est otavia and for some time have been having hesitation problems, it doesnt happen all the time and seems to happen under hard acceleration or from cold more often. I have checked the air filter, new spark plugs and the leads are good and have tested them. I ve cleaned the mass air flow meter but still the problem remains which leaves me thinking EGR valve. Where is the location of this???

have u cleaned the throttle body ?
