My Z car is in very good condition, but it has an issue that I am not sure of how to fix, as I don't know what the problem is. However, I can explain what happens.
On cold starts the Z fires right up! But it may not idle very good at first. Once it warms up a little 1 min or 2 mins it idles steady at about 700 rmpm.
Now, If I turn the car off and start it right back up it fires right up.
If it turn the car off and let it sit for more than 5 minutes, when I go to start it again it takes a while and then it fires. But when it starts the idle will bounce between 500 and 1000 rpm, and finally after a short while it will idle fairly smooth.
Also when driving sometimes it idles at around 700 rpms, sometimes around 1000. There does not seem to be anything consistent.
The car seems to have a little hesitation sometimes at low rpm < 2000 (it is not much, maybe just a little).
The car does run very well when over 2000 rpm.
The only thing not stock is the fact that the charcole canister was removed by the previous owner. The hose is just left open. Is this how it should be or should it be plugged? I did not think it should be plugged, but I am not sure.
I have recently installed new plugs and wires, cap and rotor. I have not checked the timing, but it seems good.
Exhaust is fairly new, but not the cat converter. I was thinking maybe that cat is plugged, but it runs very strong in higher rpms.
Thanks for any help,
Dan Didier
