Probably not. But a failed one will have an effect on the air pressure in the intake manifold and this could cause problems with high idle. Take the pipe off the intake manifold and blow down the pipe. It should be blocked. Take the pipe off the engine and blow down it and air should pass freely. Make sure the pipes are not split or leaking at the joints.

How do i fix the Egr valve in a 1997 Pontiac transsport?
First verify that you haven't got a clogged passage in the intake. Remove the valve and start the engine. If it starts and runs (possibly at an abnormally high idle) reasonably well, the passage is clogged and must be cleaned. Otherwise, put a new EGR valve on it. The valve itselt is not repairable.
Valve train noise big block Chevy when hot?
Engine running hotter then 220 degrees can cause valvetrain noise. Bad fuel can also cause valve noise / PINGING sound. Ignition timing to high / Advanced to far, can also cause engine noise.
What causes high exhaust temperature in marine engine?
Engine overload, insufficient scavenge air (ensure blower suction filters are not clogged), also ensure no air leakage between the blower and scavenger, expanded injection nozzles, damaged or worn valves or valve seat.
What are common reasons for a 1999 Honda CR V to burn oil?
(1) The Positive Crankcase Ventilation valve (PCV valve) might be clogged up - needs replacing. (2) If the engine is high mileage and/or has not been properly maintained, the piston rings or the piston walls may be scored and you may need an engine overhaul.
Will a clogged catalytic converter cause high degree of grit in exhaust?
Yes
What causes high oil pressure on the engine of a 1996 GMC Suburban?
High oil pressure in a 1996 GMC Suburban can be caused by several factors, including a malfunctioning oil pressure relief valve, excessive viscosity of the oil due to low temperatures or incorrect oil type, or a clogged oil filter. Additionally, an oil pump that is operating at too high a pressure or an engine with excessive wear can also contribute to elevated oil pressure. It's crucial to diagnose the specific cause to prevent potential engine damage.
Can a bad EGR valve cause high hydrocarbons?
Yes, the EGR valve, or port EGR
Why does my car dies out after i rev it?
If your car dies out after revving the engine, it could be due to several issues. A common cause is a faulty idle air control valve, which regulates the engine's idle speed and can cause stalling when it malfunctions. Additionally, fuel delivery problems, such as a clogged fuel filter or a failing fuel pump, may not provide enough fuel after high revs. Lastly, issues with the ignition system or vacuum leaks can also lead to stalling under certain conditions.
What would a bad EGR valve gasket cause?
Poor performance, poor economy, rough idle, lean burn causing valve or piston problems...
Can bad eg valve cause high oil consumption?
Yes, a faulty exhaust gas (EG) valve can contribute to high oil consumption in an engine. If the valve is not sealing properly, it may allow oil to enter the combustion chamber, leading to increased oil burn-off. Additionally, an improperly functioning valve can disrupt the engine's efficiency, exacerbating oil consumption issues. Regular maintenance and timely repairs are essential to prevent such problems.
What would cause an engine to burn too much oil?
Several things can cause an engine to burn oil, and all of them are pretty normal in an engine with lots of miles. Oil control rings are often a problem. They are on the piston and while they can be replaced, you'd be better off buying a new engine. Other things that can cause an engine to burn oil are valve seals (common) and valve guides (uncommon). If you have a high mileage engine, I wouldn't worry unless you have a big cloud of black smoke coming out the exhaust. Best thing you can do is just check the oil often.
A clogged air conditioner condenser would cause what?
high head pressure and a higher supply temp.
