Thank you everyone for your input. Here is were I'm at the moment with this problem. I purchased some SeaFoam to clean the Injectors as about a week before the Check came on my wife who drives the car, ignored the low fuel indicator and ran out of gas.I was hoping that perhaps the injectors were causing the problem. I then brought the car to an Auto Service Center I have been going to for over 10 years and they have quoted me @ $1,500 to replace the right bank Cat and two sensors. Needless to say that quote nearly gave me heart failure. So from reading the forums out there I decided to replace the Air/Fuel Sensor & O2 Sensor on the right bank ( which is the bank they're telling me is the problem, 3 Cats on this car ) The on board system was reset and I was told to drive the car for approx 100 miles and hopefully the system would remain clear. However 68 miles into it the Check Engine came back on,by the way the above work has cost me $577 so far. I also have a pending emissions test. I am at a loss now as to what to do. Looks like I'm going to have to bite the bullet and get the new Cat. Will hold off for a week or so. If anyone has any further input I would be very grateful to hear it.
Sincerely
