I'd almost put money on it not being #2, as the problem has repeated itself 3 times, and always comes back shortly after a new sensor is installed. Unless I've managed to get 3 duff sensors in the space of 18 months ..
OBD2007 shows the MAF as reading air flowing through it, going up and down along with throttle movements. Getting some MAF Cleaner tomorrow though to see if that helps at all.
Without paying £70/£80 I cant see if it is injectors or not, and if its not its £80 down the pan.
And we can't see or find any air leaks. Spent 30 mins earlier poking, tweaking, squeezing vacuum hoses with no reactions. boost pipework looks alright.
