hi folks the above vehicle giving me a bit of a headache idle is very rough. no stored trouble codes compressions and leakage ok valve timing and lift ok ignition timing ok fuel pressure and injectors checked ok ignition components ok no air leaks found. no exhaust blockage found vehicle emissions are 0.03 co 0.12 hc 4.23 o2 12.23 co2 1.2 lam [too lean] live data air flow voltage 1.9 throttle sees .56 v injector dur 4.2ms what i have noticed is that whilst ticking over i can pull off cyds 2and3 htleads individually and the idle increases but not so on 1 and 4 not using or burning water so i think head gasket is ok. sorry for the long post but any thoughts would be of great help tia damian
