1997 Lincoln Mark VIII Repair Question
Left front catalytic converter sputters. what is the most likely reason in my case??
I got to the car and cleaned the MAF sensor, checked the spark plugs & COPs, replaced the air & fuel filters, but I have not tested the injectors individually nor the vacuum & fuel pressure and have a can of Seafoam ready to use.
There is also a noise coming from underneath the front driver's side of the car, kind of like a struggling exhaust as it goes "puh puh puh puh puh". I move to the passenger side near the front wheel and I hear it slightly, move back to the driver's front wheel and it is much more distinct. I can only guess the left front catalytic converter is struggling due to my brother's choice of gas from mine and his low fuel maintenance having affected the converter or perhaps it something else completely unrelated from what I'm assuming.
Hi well i would have to say you are most likely right. if you hear a prob in that convertor then most likely it is starting to fail but not enough to effect the 02 sensor yet.as you know this is a high tech eng with a very sophiscaticated engine control system.I would have the convertors tested for backpressure and just wait it will get worse and convertors will need repaired. good luck Billymac
