Hammer Time Ultimate Carjunky / Moderator Feb 12, 2012, 7:56 PM Post #3 of 5 (1963 views) Re: corsa b 1.0 bouncing down the road Sign In There is no code that says the EGR valve or any other valve is "faulty" The codes give specific information about the circuit and it's up to the technician to further test and determine what actually caused the issue. The EGR valve is only one component in problem circuit. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

No signal or corrupted signal from the crank sensor can cause stalling and no starts. EGR valve can cause stalling, but only at or around engine idle speeds. Very easy way to see if the EGR system is causing stalling is to unplug the valve and see if your stalling goes away. That's if the valve isn't sticking open from a seized pintle. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
