Is it OK to clean EGR valve and throttle body?
It’s not a lot, more a small drip of oil from the intake air which pools at the bottom of the hose. I want to undo it all and smear some black gasket maker around the inside of the hose and then tighten it up again. any reason I should not do this?
What causes the EGR valve to stop working?
The most common culprit is carbon buildup on the throttle body, exhaust gas recirculation (EGR) valve and idle air control (IAC) valve. In this article, we’ll show you how to clean an EGR valve. This simple procedure can often bring an EGR valve back from the dead and restore a smooth idle.
Where are the EGR Jets in the intake manifold?
A more radical design, implemented in a few models, was the replacement of the valve with EGR jets at the bottom of the intake manifold. Some newer high-efficiency engines, for example those with variable valve timing (VVT), don’t even use an EGR system. If playback doesn’t begin shortly, try restarting your device.
What causes the throttle body to get stuck?
Even if you have an air filter on your car, dirt and soot come from the turbocharger, EGR valve, and the crankcase ventilation and get stuck on the throttle body valve. After a whole, it will cover the valve so much that the RPM will be affected.

What can I do to restore my EGR valve?
A good dousing with throttle body cleaner may be enough to restore your EGR valve to near-mint condition, transforming a harsh idle into a soothing hum. Hold the EGR valve so the cleaning spray drips away from the electric solenoid and vacuum motor.
What should I do if my throttle body is bad?
As a part of your regular service intervals, include the air induction service and fuel injection flush to clean out any carbon deposits and dirt. You will need to have the check engine light shut off by a qualified mechanic.
Why does the fuel management light stay on when the EGR is open?
This means the amount of hydrocarbon gases emitted from the tailpipe increases significantly producing a fuel smell. Your engine management light may stay on once your car detects an issue with the EGR valve. This could be caused when the EGR is either constantly closed or open.
