So yet another weekend will be spent by me taking something else off the car to see if I can diagnose the injector light.
Car not running lumpy at all in fact sounds and runs like a dream 99% of the time - but emissions (CO only) too high, very rarely stutters when pulling away, cold idle set to 600 having turned the brass screw which results in slightly elevated warm idle at 900 ish, but if I bring the warm idle down to 750-800 with the brass screw cold idle cannot be sustained and have to use accelerator to keep car alive when cold.
Maybe there is an air noise like blowing under acceleration which I do not recognise in my 20vt - but when I say blowing it is more like a faint poofing noise whose frequency increases with revs.
startrek still says lambda and cam sensor faults with both having been replaced.
Checked/replaced so far: -
Map sensor pipe
All induction pipes
16v NA Blitz Blue
