I will talk to my buddy but I think he still has the raw data. the last full tune up minus o2 was july of last year but recently has new fuel filter other then that it is still sitting on older plugs and wires from then. O2 sensors and pems should be here in the next month or so. then I will get more scans and soon after the high flow cat and DP will be added.

If I can..I'd suggest finding the KR before all those other variables are introduced.

And one tank of premium might be the answer. What octane are you normally using?

well I am usually running the 87 octane which is considered midgrade here in the mountaiins. but this tank has some left over 89 from the trip to NE not much but it was in there last so I am not sure. I will run premium when this tank is gone and then go from there and see how she does. could a cv joint going bad cause knock
