Got my engine going
Everything else is fine apart from one problem, with the engine idling, if I blip the throttle or even just push it down to rise the revs the engine hesitates for a second and then the revs pick up.
I haven't got a clue what it is.
The engine is standard 20xe with K&N 57i and exhaust system.
BTW the ECU light is not on. I checked most of the vacumm hoses which look ok.
