Here's the final follow-up on the right bank mis-fire issue. I ordered an aftermarket cat system for the right bank and had it installed today. Thankfully that was the problem because all is well now with no codes. What a relief!!! Many thanks to all of you that pointed me in the right direction as to the possibility of the primary cat going bad!! I couldn't have done it without your help and direction, I can't say thanks enough!!!

When they removed it and turned it upside down chunks of the catalyst came falling out of it so there was no question that was the problem. I'm going to give the left side a little time but will put it on my agenda to have it replaced as well.

Also some of you may remember a few of my first posts right after I bought the car saying it felt a little "soft" on acceleration when comparing it to the 95 E320 that I used to own, well that "softness" is definitely gone!!! She makes a screaming run to redline now with power to spare, no more softness on acceleration!!!

Again, I don't want to repeat myself too many times but, a huge thank you to everyone who led me to the problem and the fix!!! My hat is off to you all!!
