Title: Dead throttle, intermitent
Post by: Jan Suhr on 10 May 2011, 11:58:48

I have a strange problem with my '01 Z22 Omega.

If I stop the engine and start again within a very short time, like a minute, the throttle will not react to any pedal movement. The rpm is around 1300 when this happens. If I shut down the engine again and wait five minutes and start again everything is back to normal.

I have taken the gas pedal apart but it looks OK to me.

What can be wrong? Do I need to change the throttlebody?

Thanks

Jan

Wheres all the 4 pot owners?

Anyway, I'm not a 4 pot owner, but cleaning throttle body is a good move anyway. But I wonder if the drive by wire is acting up ? Believe there are throttle and pedal position sensors that can be interegated via tech 2 and live data. Any fault codes can also be checked.

If you have the facility to do so, certainly would be interesting to see live data when it happens...

Old subject but today I was able to read out codes when this happened.

P1550 Electronic throttle system (ETS) - in emergency mode
P1500  Electronic throttle system (ETS) - circuit malfunction

I also have P0170 because of a vacuum leak that I never seem to be able to find even though I have changed the intake gasket several times.

Engine was running when I read the codes and when I deleted the codes the idle went back to normal. I.e. The malfunction got deleted too.
