TKSR has me worried

[08Silverado]

Cant figure out why I have so much tksr and it kinda has me worried. Hopefully Monte or somebody else that knows can tell me whats up

wow, yeah... it kinda crept up on ya there...

there's nothing whacky in the log... everything is steady.. then all of a sudden, you get those patches of KR, and then they're gone again...

hit a bumpy patch of road???

[08Silverado]

Not at all, basically flat freeway the whole time, there was a slight incline at one point but it didnt last long and it wasnt steep at all. I'm running the 87 tune right now with 87 octane. Should I try using 89 with the same tune instead? I really doubt its the gas though.

Changed my plugs a couple months back also(NGK TR-5) is it possible they are the problem?

[06MonteSS]

if that was the problem, I would expect to see all the KR throughout the whole log... but you only have it at a particular point in the log...

Any ideas, is that enough to be a problem? I never use to get any now recently seems like its more and more frequent. Kinda starting to bother me. could it be the 87,cause this never happend with the 93

[06MonteSS]

yeah, could be crappy 87 gas... put some 89 gas in there with the 87 tune...

or, just go back to the diablo tune and 93 gas...hehe...
