Ok, so i got the guage wired (auto meter a/f guage) and it works, the question I have is at idel it sits in the last 4 yellow and every now and then it will light up the first green (rich) light. The the motor will shake and it will go back to the 4 yellow light. When im driving if I barley hit the gas nothing shows, but when i give it 55+% on the gas it reads on the middle 3 yellow lights, unless im driving with my lights on then it hops around and goes into the red. Is this normal?


The way I have it hooked up is its grounded thur the access panel and the power wire I spliced into another wire that turns off and on with the key that the prev. owner ran for a ash tray radar dector. Maybe I need a new power source?

 

It sounds like you have unshielded wire or the shielding has worn off/wire has been damage that connects to the o2 sensor. I would check that first. Then the ground, then finally the power source.

 

remember im not shure if you read the instructions but gauge does not work until car is FULLY warmed up thats number 1 number 2 gauge has no purpose unless your on WOT if not the gauge is nothing more than a light display...
