hello eveyone with an A/F gauge did you ground the wire to chassis or ECU? cause i grounded mine to chassis and it seems to give me low readings like in the .88 range, my car is completely stock right now. and i just changed the fuel filter and it appears to be running fine. so i do not believe it is really this lean, my egt's are perfect too. so i was wondering if the readings are funky cause i did not connect the unit to ecu ground!
thanks

Rest In Peace Heidi Doggy
