right ive just fitted a new x16xe as my old one gave up, i got it all fitted and it ran but it was idling up and down between 1000rpm and 4000rpm it eventually went and i drove it for a day but it was missing so i thought it could possibly be the injector rail so i changed it i put it all back together and the idling problem came back i thought it was ecu at first just resetting itself but it wont go it just keeps idleing up and down any ideas as im at the end of my teather with this car now, ive kept all same ecu and wiring, its also missing at low down revs ?

Idling could be any one of the sensors down. I suspect th missing at low rev could be something to do with the crank sensor or the woodruff key way on the bottom pulley.

Have you changed the Air flow meter? If so try your old one as this would be my first step. I dont know though i havent came across it.
