So I had been running open loop for a few months. No O2 sensor.
I knew my mix was pretty close, adjusted by ear, nose and performance.
But I missed being able to tune the mix with a dwell.
So I had an O2 bung welded into the Special T Auto Stainless Exhaust System.
Went for a long drive and hooked up the dwell, reading was way off...
So I hit the WOT / Fuel Throttle Switch, 40%...
Turned of the car jumped the rely, sure enough still 40ish%
Took the meter inside, switch it to Volt and hooked it up to a 1.5 volt battery nothing.
So my meter has bit the dust.
Any ideas on what would kill a meter like that?
