hopw do I find the egr valve on a vauxhall signum
Yes, the EGR valve, or port EGR
2001 Dodge Rams do not have Egr valves.
Would this cause the car not to start If the EGR VALVE is bad
If the egr valve was stuck open, the engine wouldn't idle. If the egr valve was stuck closed you may hear excessive pinging (spark knock) and in most vehicles, the check engine light would illuminate.
A bad EGR valve in a 2000 Saturn can have several symptoms. The EGR valve can cause misfires, the valve can cause vacuum leak style problems. There could also be an engine knock.
Sometimes
No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
yes
If the egr valve is stuck OPEN - the Engine will run Very rough & idle bad - or not idle @ all-if the egr valve is starting 2 stick IT WILL TURN ON THE CHECK engine light-Sometimes U can take the valve off & clean them with a GOOD carb cleaner.
Start the engine, and spray a little carb cleaner around and on the EGR valve. If the engine changes sound are idles up are down then the valve is bad.
Depends on the vehicle. They usually do not go bad. I know that some vehicles are pron to EGR problems, not the valve. The EGR port gets clogged, causing a vehicle to run poor. The port can be cleaned, I just had mind done on my 2000 Accord V6. The vehicle has not sputtered or had a bad start since.
