Is it a Diesel?

 

They aren't subject to emmissions testing. Just smoke/smog testing? Does it smoke @ idle and under a little throttle?

no petrol

here have a virtual cuppa tea sounds like you need one.

 

not sure what car you have

 

so a reminder to check your sparks and check you havent overfilled the oil .

then its lambada sensors cat, and holes in exhaust

 

local taxi's diesels use a tonic which put in tank to make it have low emissions

 

 

Also worth putting in injection cleaning additive added to the fuel tank

 

 

then before retest brake heavely using gears to slow to jolt sticky valves and run engine till hot before retest
