Car emissions advice

Could well be O2 sensors failing that is where I would start but normally they would throw an engine light.

It needs a scan to be sure, could be just general accumulation of wear and tear. Things like MAF, engine EVAP system. Vacuum lines, Air leaks even a compression test 

Good Luck

Quick update after a long pause….. 

filled it up with premium unleaded and redex and took it for a run…. Did this all week til it ran through the fuel and then repeated. Took it for an hours drive before the mot and it passed its emissions test. 👍🏻👍🏻👍🏻
