i dont appear to have a lamda sensor anywhere in my decat system but scooby (95 import)runs fine and gets about 240 miles on a tankful. could there be a bodge somewhere fooling ecu or should i look for the sensor elsewhere, maybe before the turbo?

 

The 02 sensor is in the RHS of the exhaust manifold on an import, not the downpipe

 

ah thanks for that. guys at the mot station didnt know. i am lucky its an import is all they said as it didnt need to pass emissions test. will definitely be going there again
