can any one help. this vehicle has a missfire at tick over which seems to disappear when revving.
there are no fault codes and no mil lamp. have eliminated coils. at idle co 4.8 hc 326 lambda ok, at 2500 rpm emissions normal. at idle vacuum a bit low fluctuating quickly between 17 and 18 in.hg. compression test ok, but no. 1 plug gets very sooty. would appreciate any help, dave.
