Munching petrol

Ok, heres a few interesting things..

I got the oxy sensor cranking again today, and when I rev the engine HARD, it goes from lean (it seems to run slightly lean at idle I believe), to super-rich, then jumps back to about midway, then super rich.. and just keeps bouncing around like this with the throttle opened up

Does this mean anything to anyone? Eg. does this happen when a certain sensor is ****ed / not plugged in (apparently the LPG uses the signal from one/some of the sensors, and its possible the petrol no longer receives these signals, or so I've been told)..

Next interesting thing.. If I let it roll along idly at ~60km/h, petrol consumption is around 3-4l/100km (probably right?), give it a TINY bit of throttle.. maybe 1/25th open, and it jumps to 10-12, tiny bit more, 15-20, and if I go WOT, it can get up to 72L/100km (this is on the instant l/100km on the trip computer)..

Once again, is this normal? Anyone with an early e-series, with a working petrol system + trip comp, reckon you could just gimme some basic figures for what you get at idle (car must be moving btw, when idle and stopped it will just give 99l/100km constantly I believe).. at a bit of throttle, half, and WOT?

Thanks :)

Re: Munching petrol

Sounds normal jamsey.

My AFR does the same thing, flashes between rich and lean constantly at idle, goes full rich under acceleration goes lean on decceleration. When it goes full rich its actually changing from closed loop mode to open loop. If I am on a flat road and give enough throttle to slowely accelerate I can actually feel the car making more power as it goes to open loop mode.

The figures you quoted from you trip computer seem to be fine.

Re: Munching petrol

No, you didn't win because you have a 3 speed CFI.

James, that sounds about normal. Mine did the same thing back when I had the EB ECU in. Now the trip comp reads 89.7 litres per 100. I really need to fix that.

Re: Munching petrol

Has anyone here changed their driving habits since the price of fuel went up? I'm driving like I would if I had no brakes or accelerator pedals
