So I'm getting less than 13mpg all of a sudden. The idle is all over the place (probably a dirty TB) and I can smell it running rich. No engine codes though. Planning on dropping it off at Toyota for a full tune up and valve adjustment. Anything else I should consider doing while its there?

 

Afraid I can't answer your questions, but are you still planning on getting rid of this rig? Why not let the next owner worry about it? Better resale value?

 

when my mpg faceplanted (roughly 7 mpg) It was my stock afm. Put the supra afm in and poof. back to normal. just my personal xp though

 

I don't like selling something that isn't in good condition, karma and all that. I did clean out the throttle body and the idle is back to normal. Doing the re oiling on the filter this weekend and replacing the plugs since the filter is jacked up full of powder from the job site and its running rich. Wrong plugs last time I changed them. Will be getting the valves done next week along with a rear main seal/clutch. Thr seal started leaking and now I can smell what I think is oil burning on the clutch disc, clutch is also slipping a tad. Hell I might have to keep it for another year after all this.
