Celica Forums General Discussion General QUESTION/HELP A/F GAUGE

I installed my Air/Fuel Ratio gauge but it reads weird. If I am driving say on the street just holding the gas going constant speed it jumps from red to almost rich and keeps repeating that, but as soon as I punch the gas it reads nothing, Nothing shows on the gauge, as soon as I go back to just holding the gas normally it starts jumping reading again. Wondering if anyone has any input or dealt with this before. Thanks

PS I have the APEX'i Power FC, could that be the problem anyone have the APEX'i PFC and AIR/FUEL Ratio Gauge??

hmm, wish i could help, only thing i could think of is that i heard that it wasnt going to work very good on our cars!!

you need a wideband o2 sensor

or atleast another o2 sensor wide band can be expensive

What does a wideband o2 sensor do/work? Where cand I find one and how much do they cost?

Thanks
