No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
Yes, a faulty catalytic converter can cause fuel consumption to raise. Replacing a known bad catalytic converter will help, but keep in mind, the catalytic converter usually does not fail on its own. converters are pretty tough, living their lives running at 2000+ degrese internally. I would check your EGR valve and EGR valve tube for blockage or carbon build up. a faulty or clogged EGR valve will overtime distroy a catalytic converter. second thing to check is your Oxygen Sensors. these sensors are the computers first reading of bad fuel mixture, if they are clogged with carbon, they can distroy your EGR valve, which inturn kills your converter.
Probable cause is exhaust restriction, possible plugged catalytic converter.
It does not have an egr valve it has a 3 way catalytic converter.
An EGR valve reduces oxides of nitrogen. Cat converter reduces high HC and CO
A restriction in the catalytic converter will cause the EGR solenoid to melt on a 1995 Ram.
No, it is no different than removing a catalytic converter.No, it is no different than removing a catalytic converter.
Catalytic converter plugged?
excessive exhaust back pressure, possibly a failed catalytic converter
fuel filter
Fuel filter.
Restriction in the catalytic converter.
M o st likely cause is a restricted catalytic converter.
