Technical question. Just wondered if any obvious tips or sage advice before I tear the thing apart.
In the last few weeks, (UK, winter) t’Jag has developed a bit of a misfire – only when cold AND under load from low revs. Once half warm runs like a dream. I hope to get an hour or so to fettle the usual – all wiring is good so far as I can see, fuel filters are clean (but I will check again) and I suspect either air leak at inlet manifold (which clears /closes up when warm) or a duff spark plug (which again clears into life when warm). Truth be told car has only run once or twice a week recently, and it might be a bit of damp that needs to burn off somewhere. Twin SU’s, electronic ignition, Shell expensive fuel, recent plugs, good leads etc. engine rebuild 6000 miles ago, all good, everything else tickety boo.
Comments on the back of an internet please.
