: Unfortunately the coil packs ended up not being my hesitation issue as I was using a faulty ohm meter. I need your advice if would have the time. I've been having hesitation issues which are: when I'm driving the Z under 3200 rpm it feels as if one or more of the cylinders isn't firing it's happend at idle but maybe only twice, bad gas mileage, fuel pump buzzing while idling and driving (always on) but feels pretty good under wide open throtle and last night could not start it, engine would turn and sounded like it wanted to start only for literaly one second, as if the fuel pump relay was disconnected. :Oh yeah kind of loud popping from exhaust when down shifting above 4500 rpm : :Your help would be greatly appreciated : : :Lucian
