Hi, new member with an astra coupe 2004 on 148k.
Have owned for 2 years without too many problems. The problem I'm having now, is a rough idle and when left to run for a few minutes the abs light comes on and the revs rise to 2k.
The error code given is p1415 air flow to tp sensor correlation to high. I've swapped throttle bodies, fitted new plugs, removed the egr all with no change. The inlet manifold doesnt appear cracked and there's no vacuum hoses disconnect.
Im going to do a pressure check later too as a precaution. And other ideas? Thanks.
