well another day poking around with it and still no further forward...
put another maf in it today incase the one fitted originally was dodgy, but still not solved
so far we've replaced:
took out injectors and cleaned + regulator
changed vacume pipes
cost me around 300 quid so far and still no joy!
it runs 99.9% fine on idle and you can drive it all day long just poodling without a problem but as soon as it comes onto bigger boost it misses and mucks about!!
we had it running earlier and were looking about under the bonnet as my mate is sure its a boost leak although we cant seem to find one, however we noticed when you rev the car the dv (forge split-r) doesnt seem to open or close and it just closed all the time even tho the vacume to it is working fine, you can wind it out so the gap/ piston is open and it seems to drive a hell of a lot better yet still misses under heavy acceleration!! can the dv cause this sort of problem? or am i just pointing at stuff hoping?!
i need to get this sorted as its driving me insane!!!! any help greatly appreciated
its an APY engine
