Car has missfire,on one cylinder,seems to be number 2 cylinder.popping badly out of exhaust,on test drive missing + hesitant but not flat.so does not appear to have blocked catalyst.read fault codes only one in memory saying immobiliser fault. compression test good on number 2 cylinder. plugs replaced & all leads swopped round to no avail. vaccum test done,good vaccum 19hg.blocked off servo pipe,still no good. emission readings all good co:0.04%.hc:040ppm. o2:14.50.oxygen:0.89.lamda:1.04. on fast idle even with missfire can achieve lamda 1.coil pack on these sat on top of engine all readings as per autodata book correct. yet pull plug lead off number 2 and it has little affect.any thoughts welcome
