Put the silicone hoses and induction kit on today,looking good (after an hour of ******* about that turned out to be a bad earth! On the started position on the key the cooling fan came on and the engine didn't turn,turned out there's a bad earth from the gearbox). It runs and revs up no bother but it idles ruff and has a fault code 'electronic load detector (ELD) which from what I know controls the alternator,I wouldn't think that would make the engine run rough though? Any ideas ha.
