Hi All , I am trying to tune my car up , Timing etc , On idle I could tell it was missing so I took A1 lead off and the engine did not change at all but a good spark,So I tried with all and to my Surprise the same with A4 B3 B2, but when I rev a little or hard sounds well. Looking at firing order A1 B1 A4 B4 B2 A3 B3 A2 , I have one is O.K and one not??? Could this be serious?? Bye the way which four cylinders to A and B bank carburettors feed I know the feed two on each side each but which? The car has been stood for 10 years .I have changed distributor cap ,plugs, the little Su carb filters are missing perhaps they took them out because they were dirty.

Your problems have been covered by Bill Coburn in past issues of "Tee One Topics" - the rough idle is most likely a vacuum leak and will require some detective work to find its location.

Thanks for your reply , But I cannot seem to find anything related to rough idle in tee one topics! Do you know how this is listed please? also can a simple vacuum leak make 4 pistons do this?
