Plugs are black - faulty lamda
Posted 17 June 2017 - 03:03 PM
When the car runs it smells very rich and is quite smokey.
On the 2e it had a 2 wire lambda and ov the 4efte one is single wire.
Is it likely to be faulty lambda?
Pretty sure I traced the correct wire to the ecu for the sensor.

Running no lambda and a faulty one are 2 different things. If there's no lambda plugged in then the ecu knows that and runs a slightly richer map for safety.
If the lambda is faulty giving wrong readings then the ecu will try to fuel according to that reading.
My lambda sensor was reading rich constantly so my ecu was underfuelling the car causing it to run like shit. Unplugged the sensor and it ran fine.

Could just be my car but never noticed a difference. With or without idled at 14.5-15
