Fix Ford Escape EGR valve problems
An engine backfire can produce enough pressure to make an EGR valve explode. However, if the engine is running rough and lacks power, suspect a plugged exhaust system or destroyed catalytic converter. When those exhaust and emissions system components fail, the increased back pressure can force additional exhaust through the EGR valve. That can burn a hole through the EGR valve which eventually weakens the valve and then it’s Ka-Boom!This is a common problem on these Ford V-6 vehicles.
Unscrew the oxygens sensor and install an exhaust back pressure gauge to check for pressure. Or you can use a regular vacuum gauge to see if intake vacuum is too low at idle and higher RPM’s. But if your engine lacks power, you can just about bet on a plugged exhaust component after an EGR valve failure.
