Right fitted an engine from a gt into my glanza, thought all was well, until I started it up, it's running very lumpy on tick over, it revs fine but if u try hold the revs it runs lumpy to, the exhaust note doesn't sound right either, it has spark on all 4 plugs, I tried loosing off the distributor and adjusting the position but no joy. Anyone got any suggestions what to check next? Everything's plugged in, no broken wires from what I can see, engine no light on the dash. Not checked the timing yet but will do tomorrow, anyone got any idea what else to check? Thanks
