Thanks a mill..
My younger bro has a mint Pug 1.9..
Yes a dreaded cat and oxygen sensor is present..Maybe its just a coincidence..
Its no so much that she is losing bhp..She just wont rev out fully when warm and struggles to accelerate and my plugs are covered in black soot..I thought it was over fueling and already changed the engine temp sensor but problem is still there. Then I asked myself could it be changing down to a standard exhaust has upset the apple tart.
Would it be normal to reset the fueling when installing a bigger pipe.?
It has an ECU..So how would one reset it to normal for the standard exhaust..
Thanks again,
Morg.
