Hi folks where is the EGR valve on a 1.8 16v ecotech astra please?
The reason i ask is, the astra will hesitate and splutter as it picks up when, the throttle is pressed do to the floor. This is usually when travelling up hill in 4th/5th gear.
I have replaced the plugs, leads and fuel filter and still no joy.
There is no ecu light on the dash either.
Any help advice greatfully appreciated
