I've fitted a 1.4 nv engine & i'm getting flat spotimg after 3.5k. I've fitted the 1.2 exhaust manifold as i only have a 1.2 system. But the car that had the engine previously was the same ,ie flat spotting.
Things i've done to the engine are nothing. I will however fit a new 1.2 head & 1.3 inlet & new gasket & so on.
But what could be the causes of the flat spotting. Oh yes i have redexed the carb while driving along but still the same.
