Hi guys,
I've recently had the top end of my Mitsubishi 6A12 MIVEC engine apart.
So intake manifold, Y manifolds, cams, cam trays, valve springs, timing belt, fuel rail, injectors etc were all out.
Heads remained on the block
I've assembled everything and tried to start the car however the rpm are hunting.
I've disconnected the idle speed control valve and it made no difference.
What could this be?
Would a misaligned crank or cam sensor cause such issues?
Besides the hunting the engine is smooth and sounds fine (I did a tappet adjustment as well).
I don't think a vacuum leak could cause such hunting could it?
There is a slight injector leak as well where the o-ring didn't seat properly but it is very minor
