Fuel Gauge Issue [LPFP related?]
On 3/31 I had my LPFP replaced for the known open campaign.
Today on the way to work, during heavy acceleration, the fuel gauge goes haywire! It goes from current fuel level, ¾ to ¼ and then to 0. Once the engine is back to cruising RPM, the gauge goes back to ¾. I was able to reproduce the issue consistently this morning and I documented with video. I just spoke to my SA and I will be dropping the car off today. Has anyone seen such an issue? |

Funny you ask! Yes I do, for about 3 weeks now and last week I installed the upgraded OBDII cable. I removed the JB4 and the issue is gone! So this is caused by the JB4???
