I've had a fuelling problem for ages that i can't find the cause of. Its basically missing on the left bank and concequently lobbing lots of fuel out the pipe.

 

The top pic is the left o2 sensor results (in white) and the bottom one is the right o2 sensor. Can anyone make any sense of this?!

My guess is that your LH O2 sensors is dead, the RH one seems to be working ok. Kinda tricky with no scales on the chart though.

Have you Checked all the coil packs and spark plugs on that bank?? As andy said o2 is dead, but it could have been killed with overfuelling on that bank. Get an a new o2 in there and take it from there, if she still over fuels you've a bit of investigating to do :-)

This I know, I've already changed the PTU, Coil Packs, O2 Sensor, and tried (and failed) to loacte the source of the problem. I've even cleaned every single coil pack and injector connector. I give up, I've no ideas left! Any clues guys? I'll record the car in a minute and see what u think.

Have you checked the cabling to the O2 sensor ?

 

I had a misfire a while back which turned out to be a broken (or failing) injector wire down by the ECU.

Er no i haven't, but when i changed the o2 sensor my readings were different for about half an hour til the overfuelling killed this one!

 

If i had a dodgy injector wire surely it wouldn't be overfuelling would it?
