What are the symptoms of a bad EGR valve? EGR tube is clean.....
I just resealed the front timing cover again, changed injector seals, changed IAT sensor, plug wires, checked every vacuum line in the engine bay.......i cannot figure out why my engine has a rich smell to it.......my new O2 sensor lasted 2 months, and i am getting a code for o2 again......
when providing vacuum to the valve (by mouth
), i could not hear anything moving or clicking.
There is nothing else i can change in this car, seriously...I just don't like the exhaust smell...I even smell it when opening the door which makes me think something is leaking in the exhaust/ egr system.....
thanks
