[DC2RKID]

who knows anything bout the crank shaft fluctuation sensor? cause thats the code im gettin....i read up it picks up missfires...but wat does it do with that info :S and theres no ecu light on when the engine is running

am now ...did them again and they were perfect... this time i didnt start it for 2 days..so motor was dead cold...

[DC2RKID]

what effect does say 110 octane fuel have on the 02 sensor

[tinkerbell]

i doubt it is good for it...

depends on brand too?

100 octane fuel from servo on sunnyholt...and nulon pro strength...but it wouldnt be the 02 cause it runs like sht from cold... plugs are still bright orange after changing them to new ones the other day with a fresh tank of 98... did a comp test and all four cyls are dead on 250psi...so no burnt valves or anythin... goin to try changing the fuel filter ...maybe its restricted.. i clamped the fuel return line off and doesnt run any better... so fuel pressure is fine... startin to piss me off really bad i hope i suss it all out soon

[DC2RKID]

thats after 3 days of normal driving..nothing over 3000rpm.. with 98 fuel

can you re-describe the problem?

like during start-up and whilst during then driving?

[tinkerbell]

i start it of a morning then after bout 20 seconds of idle start to feel the miss....start driving it and as i come to a set of light the revs drop down to 600rpm area..whilst missfiring intermitantly...and it feels really gutless as well ..the pod aint a droney either is sounds muffled

bad sparkplug lead?

static dizzy timing?

bad dizzy cap or rotor?

bad injector?

new cap new rotor ..if it were bad injector why do all four plugs look same... and wats static dizzy timing

[tinkerbell]

..if it were mis-firing why do all four plugs look same?

the position of the distributor in relation to the camshaft is 'static timing', i.e. set with timign light...

lean out.... once it starts reving it doesnt miss a beat its just gutless.... might change fuel filter but we have no Z463 in stock anyone know anything interchangable
