Lasr couple of times I've driven the Z its just felt a little different to normal on start up. Its as if there's no "choke". Revs don't rise any higher than normal temp running conditions. And the revs don't seem to rise at all for the first 3rd of travel/press on the accelerator.....sometimes bursting into life if it does. I've got a new TPS and have recently checked the voltage but not since this problem though. Should I be looking at the IAA valve? After a couple of mins driving all is fine, once its up to operating temp. Nothing too major but its annoying me, know what I mean?

 

Any help appreciated as always.

i did have a problem with my TPS as i tried ajusting it,with no voltmeter DOH? and when driving you could put your foot down and no acceleration then all of a sudden i nearly went in to a brick wall as all the power came at once and i wasent ready for it if this is happening whilst parked up,then i dont know.Worth a check on the TPS voltage though mine was reading 0.87v which is a tad bit high.isent it meant to be between 0.4-0.5v ;)

I think it should be 0.44V at idle, IIRC

Temp sensor might be dicky so ECU confused whether it should be running in cold mode or not?

I was thinking temp sensor but new sensor and harness a few months ago. Will check though, cheers. Not sure about TPS, doesn't explain why its ok when up to op temp. Again, will check all connections.
