lean at idle only
Hey guys,
I am having an issue that I can't figure out: The car is running lean at idle (16-19 AFR). As soon as I give it a little gas or drive, it reads normal. On cold start it also reads normal. There are no vacuum leaks. I can't hear any and I went thru and checked all the vacuum lines. There are no popping or crackling (I thought DI seal failure at first) Logs http://datazap.me/u/woode87/lean-idle?log=0&data= |
Need logs for sure. Get these at a minimal:
direct injection time, port time, short term trims, long term trims, rpm, manifold pressure, maf v, mass air flow (g/s), intake temp, coolant temp, oil temp, engine load, atmospheric pressure |

@nelsmar, I uploaded a log, I had to change it to .doc to upload. You can change it back to .csv after downloading.

Staring at the log, the only thing I see that correlates with the AFR is my DI time sort of
The car makes pops very occasionally at idle... I always thought DI seal failure was more often and didn't cause lean conditions though.. so I am assuming this isn't the problem? This is turning out to be a pain in the ass. I need to drive my car back to NJ from Texas in 2 weeks and this happens.. :bonk: |
