HELP !! Ok so I’ve got a 2001 gv with a j20 engine
It’s chasing ocasanly on idel and intermittently loosing power it also comes up with fuel system error closed loop and is running rich also in getting no engine codes ... I have changed air mass / cam sensor / throttle position /temp sensor/ checked the egr / changed sparks and coil packs and am now running out of ideas

In case anyone was wondering it was shit in the fuel tank and a fuel pump on the blink

Glad you got it sorted hope you've put a new fuel filter on!
