Hi Everyone
My MPI started running very rough under load around a week ago. After a bit of fiddling I replaced the plugs, leads and coil pack. It now idles better but sounds rich (popping on the exhaust)
If I try to drive it it's not perfect but after a few minutes it sounds like it's running on 2 cylinders and has almost no power until it won't hold revs and cuts off.
I have had it plugged into a diagnostics and the numbers for MAF etc seem fine but the lambda sensor is not reading correctly. I replaced this a few days ago and have confirmed that all the pins are getting power.
Could it be a faulty lambda sensor causing my issues?
Thanks!

In your photo it shows only 47 degrees so the engine isn't warmed up or it is reading incorrectly. The battery voltage is also low which could indicate a poor earth to the ECU. Until the engine is up to temperature according to the ECU, the O2 sensor being bad shouldn't matter.
