Hi, looking at yet another engine for me, its a 115 V4, so i have seen the engine in the flesh, its runs very smooth not missing or messing about, good compression on all 4 cylinders, BUT when under load the left hand bank is low on power, we did a few tests, and it has a weak spark on that bank, easy fix ? is it just new coils ? are they exspensive ? over to all you experts for advice , ( only had old pentas and chryslers in the past )

regards
