I have 1/2 tank of 91 and 1/2 tank of 87 octane gasoline. I really don't think it was the key player. Install the new CAT is a very easy job. I end up removing the muffler first then the CAT. This operation also give me the opportunity to replace the drive side oil pressure sensor. I was not able to remove this sensor befoer. Too many things are in the way. rendy 4220 > Great news - BTW, did you have regular or premium fuel in the tank? > > Harold McElraft - 3354 > > > --- In dmcnews@xxxxxxxxxxxxxxx, "rendycheng" <rendycheng@xxxx> wrote: > > ## This is from the original poster ## > > First of all, I would like to thank everyone helping solving the > problem. > > > > This is my final report on my smog problem.
