  1. You have been busy! 6 kids and this thread is 62 pages. Did you ever replace your coils? just curious.
  2. try drinking your beer with a coiled up long section of hose - should help the stumble/stutter
  3. Slowing it down sounds like a good idea. You could also try applying a dab of metal polishing paste periodically to the stone. Personally I would be concerned about using the discolored buckets as the metal may behave differently.
  4. that seems like a great setup! not sure about the discoloration of the top of that bucket though - I haven't seen one that looks like that before.
  5. The grinding stone leaves a fairly good surface imo. But I did try a couple different methods by hand after grinding, like using a small piece of fine sandpaper on the ground surface, or using some metal polishing paste. There's not much surface area on the nub so it's pretty easy to polish it up a little if you want to.
  6. Hah! Sorry I should have documented it! It was a ton of work as I bought it with a spun bearing, blown turbo, growling center diff, leaking power steering rack, to name a few issues. I spent the summer of 2019 fixing all that, new shortblock, turbo, fuel mods to support e85, etc. Oh and many valves were too tight so I used the method in this thread to adjust them. Now it's running fine so I'm bored - maybe I'll get lucky and the engine will blow up
  7. Personally I usually shoot for the looser end of spec. But if they are set too loose they get noisy.
  8. No problems so far, but I did sell the original LGT that I performed this style valve adjustment on. I did the same on my current 09 WRX about 2 years ago and it's running great <-- tempts fate Regarding mods, both cars were on E85, 20+ psi, running new oem shortblock except for opened up ring end gaps (another mod I always like to do, for reliability).
  9. Sometimes you can reproduce a clunk by standing next to the car, open the door and lift it up and push it down - basically rock the car using the door as leverage. If you can hear the clunk then maybe you can try to isolate where it's coming from.
  10. also, under the hood, check if the nut on top of the strut is tight (usually under a small plastic cap)
  11. maybe the day you eventually replace your floor mats, the misfire will go away.
  12. Could be timing. Just figured it would be an easy thing to try to add a little damper to the FPR signal line, if anyone is still having these issues. I'd try it myself, but i sold my car a while ago, and it no longer stumbled anyway
  13. Thanks, I did do that years ago and it helped tremendously. But I still see people occasionally posting about still having some stumble even after having done that (and switching to an 07 FPR on earlier models). Just wondering if those outlier might want to try a damper on the FPR signal line - just a wild guess of an idea
  14. Not sure if this has ever been attempted (many many posts on this stumble), but has anyone ever tried to put a "damper" on the FPR signal line?
