Hi, Have been restoring 1977 MK1 V4 2LTR .Engine was running ok before restoration of the body. Engine was not touched apart from being cleaned up and painted. It now has a misfire on no 1 and no 4 cylinders. New plugs,points and condenser.coil checked, distributor cap changed.Rotor changed Have switched the no3 and no4 plugs around, no difference. Changed the lead on no 4 ,no difference. Spark is weak at no1 and no 4 plugs. When these leads are removed temporarily it makes no difference to the engine running. compression test done on 1 and 4 cylinders and is ok. ht leads and lt leads checked and ok. I put in the old plugs for 1 and 4 cylinders. NO change. Have run out of ideas. Can you help
Don
