  1. Extremely High STFT LTFT and P0171 code

    Common problems that trigger the P2187 code... Damaged or contaminated spark plug Fuel injector failure Powertrain Control Module (PCM) issue Vacuum leak Exhaust leak Fuel pump failure
  2. Is a .2 voltage drop overnight normal for 2018 civic?

    I'm not trying to give you crap but why ask here? You shouldn't be seeing voltage in the 11's with a new battery. I mean, you just bought a battery from a dealer 3 months ago and it already conked out. You should be at the dealership right now having them take care of it. Honda batteries...
  3. Extremely High STFT LTFT and P0171 code

    Honestly, I'd think that's gonna be kind of tricky considering he's been tuned and the extent of his mod list.
  4. The Tuned CivicX Experience & Reliability Thread (for all models)

    @Enzym 5AN-*** is the important number. It's a non-issue.
  5. Extremely High STFT LTFT and P0171 code

    You might be right but usually with injectors the wonky fuel trims are accompanied by misfire codes which he never got.
  6. The Tuned CivicX Experience & Reliability Thread (for all models)

    Actually fuel trims look really good in both logs. Second one is a bit better though.
  7. The Tuned CivicX Experience & Reliability Thread (for all models)

    I was able to track down that old edited post from the guy I mentioned the other day. Sadly, it's another hatchback rod failure (#14). It's mind numbing that 14 of the 17 (82%) Non-Si rod fails are FK7's. I also added his car to the failures thread...
  8. The Tuned CivicX Experience & Reliability Thread (for all models)

    That's odd. If I was to create a new Starter tune, I see this: Contact [email protected]
  9. Extremely High STFT LTFT and P0171 code

    I didn't realize you brought it back. Sorry.
  10. The Tuned CivicX Experience & Reliability Thread (for all models)

    Are you opening a "Starter tune"? The "Stage" tunes are mostly locked and won't have much you can touch.
  11. Extremely High STFT LTFT and P0171 code

    Take a 30 minute drive and see what LTFT looks like at the end of the drive. Do a log and post it here.
  12. Vibration at traffic light.

    Stock, our models have a very low idle speed (it's to save gas). When the car reaches normal operating temps you may see idle below 700 at times. I experienced this. My front passenger seat would literally shake at traffic light stops. There's nothing wrong with your car, that's how Honda...
  13. Stock wiper blade housing - do they last long?

    I use the OEM inserts and replace them once a year. They could go longer but it's just habit I guess.
  14. The Tuned CivicX Experience & Reliability Thread (for all models)

    I always use a trickle charger (Battery Tender) while flashing a tune.
  15. Extremely High STFT LTFT and P0171 code

    I've been nothing but impressed with the Rutheniums.
  16. what MPG does your gauge cluster read for your average fuel?

    @cheezer4998, a couple things. First of all you added your car to my tuning thread two years ago when you first tuned. Could you please add a new post there with your current info (tuned miles driven etc.). It's really a big deal...
  17. Extremely High STFT LTFT and P0171 code

    Hmmm. That's a little scary on the plugs (I have Ruthenium as well). I torqued mine to the OEM recommended 16 ft. lbs although I'm sure 15 wasn't an issue. I haven't heard about any problems with the Rutheniums until now. Glad the PCM was covered under warranty.
  18. The Tuned CivicX Experience & Reliability Thread (for all models)

    That's why I sheepishly said "how's the coolant level?". When I put the misfires and stuttering together with cold start wonkiness it started to make sense. Plus most of the 10th gen head gasket issues have been Si's driven hard on higher powered tunes. I think the consensus is to get another...
  19. Extremely High STFT LTFT and P0171 code

    The suspense continues...
  20. Upgrading from CVT on automatic civic

    That's fine man. You have to understand this is an enthusiast forum and you're original post talked about "needing torque" so we responded accordingly. I get it now. Thanks for the explanation.
