ignition timeing R34

[rainster]

does any one no how to check ignition timeing properly as i have found pick up wire for timeing light iductive pick up lead to go onto and have checked timeing mark and from what i see is that my timeing over advanced it is at least 20 digrees which is very high is it possible that with this model do i have to bridge my diagnostics plug or something as i think the computer is controling the timeing and i need to check acurate timeing i pretty certain timeing is ok as cam sensor shows no sighn of being moved and engine does not predetinate or any thing but very curiouse that with this model you need to use scan tool to put engine into tune mode to carry out the check.

disconnect the aac valve and the TPS and you will be in business

At least for the GTR's anyway but i assume they are all the same

cheers for that guys i will check it out hope it works as i prefer to service my own cars as i dont trust garages hear in nz as they are just to slap happy i see it all the time as i am a diesel mechanic the only problem is my car has warranty on it and i have to have it serviced by a nominated garage.I always check my car top to bottom after its had a service .pretty sad isnt it ,what happened to good tradesman these day.

hey thanks guys i did what u said and sure enough it did the trick stoped the viabrating when you are in drive cause my idle speed was not set right had to higher idle and lean idle mixture,set idle speed to 650 rpm recheck timeing all apears to be correct now
