Cragus Posted August 13, 2009 Share Posted August 13, 2009 Ok, so I am just back from the states and the Z has been on its lonesome for two weeks. I get in it to drive it today and when i am releasing the accelerator pedal it sticks to that rev range for a moment before starting to drop. Also its idle rev is much higher than it was before I left. Its making the drive really jerky when sticking.... Any ideas or is my Z just having a tantrum?

Cragus Posted August 13, 2009 Author Share Posted August 13, 2009 What does this mean? I need a new one? Its still under warranty although it has a pop charger on so should i remove this before taking it along? Quote Link to comment Share on other sites More sharing options...

Cragus Posted August 13, 2009 Author Share Posted August 13, 2009 Thanks for the suggestions guys! I tried the resets to no avail. When i start it up it initially shoots up a little past 3000 rpm without me touching the pedal. Also when i rev it at idle it sticks a little when i let the pedal go but also on its way down. I am stumped and its bugging me. Might be my imagination but when you turn the key without starting her up i think there is a slightly harsher noise coming from the engine.

P15UL T Posted August 13, 2009 Share Posted August 13, 2009 hope you and the missus had a good holiday matey, sorry to hear about your bit of bad luck and hope you get it sorted soon Paul Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted August 13, 2009 Share Posted August 13, 2009 the TPS is linked to the intake. the butterfly valve can occassionally get a bit sticky. hence the throttle opening and staying open etc, might just need a new itake section, the bit that attatches to the plenum before it goes into the intake.
