VZ Rough Idle - fixed

[Commydo]

Just go to wreakers and get a secondhand one, they give you 30 day warranty.

Ah right,fair enough,I never thought about that,
See how I go,I doubt wreckers will charge much,hopefully

The throttle body can be recalibrated using the tech2 or a Snap-On diagnostic interface. It accesses the motor. The peddle can’t. It is no motor and only sends position info to the throttle body motor.

That's right its a sender, like everything they do wear out. If its not holding steady speed that means the sender is dropping out telling the motor to rev down, its only my theory. Cant be the throttle motor or it be doing it at 100 as well. Should of stuck with old school, cables don't fail well not as much as electric component's.

Hi all, been busy with things lately and haven't checked in on this thread in some months. My VZ is still running fairly smooth since I replaced the coils. Idle improved a little more after I cleaned the throttle body and MAF (the MAF cleaner was quite expensive, but is a must for cleaning MAF sensors). Someone was asking earlier where my coils were from - answer is eBay...

hey im wanting to clean my throttle body and maf any chance u can give me the steps on how to do this?

An old thread BUT it fixed my issue. Same deal, missing heaps at idle, missing every now and again when driving. New coils and plugs fixed the issue.
