recenlty came over from the c20let onto the z20let in an astra coupe(51 plate)
cars runnin bailys dump valve (read the posts about the probs the can cause, so tried with the std on, without it etc, still same...
so... whats a common fault with them to make splutter as accelarate? or sit at half throttle in 3rd/4th gear for example (thats why done the dump valve test)
air flow meter?
water/injection temp sensor? (know they were bad for going on the ed-tops)..
changed plugs.. (off top of head cant mind what got in it at mo, copper and somit else)
and changed the coil rail.. number 4 was all brown on the rubber.
no error codes have came up, just doing head in, with a code would come up, then might have an idea whats up..
cheers for any heads up/help
