Hi all,

I got an EK4 B18 GSR swap and upgrades. I got a Hondata S300 and we already tuned the car since 3 months. In the morning today, while driving my check engine went on and after that my Air/Fuel reading went to 10.0 and car started to switch off. I parked and paused 5 mins and started again, it went up to 14.7 but I can hear a little clicking sound near my dashboard and the value goes down to 11.7-12.1 and at times 10.0. But when the sound stops it goes up again to 14.7 and sound can be heard back and it goes down again. Any idea what can it be? My tuner not readily available for the moment.

 

Check battery cables and sensor harness plugs
