Any difference in smoke ,cold and warm engine?
Does it smoke warm ,at idle or just on acceleration?
What grade oil are you using?
You car is still relatively low mileage ,at 80k,but given that everything else been checked and especially the injectors being on acceptable parameters(they should read near "0" ,min-max -1.5 to +1.5 at idle),I hope its not Turbo !
Can you tell me if when the injectors were tested ,was the EGR system (especially vacuum) connected?.

Has a full diagnostic been done on the engine?

Can you disconnect the MAF (airflow meter).Just remove the front engine cover and pull out the plug with the help of a small screw driver.Drive the car and tell me if there is any difference to smoke or performance?
