Have a 83 280zx, I am having a problem with the idle goig high around 1800 or higher when I come to a stop.I have replacrd the air resonator with a used one but it didn't help.I guess it could have been bad too.What else should I look at for this problem?Thanks for your help.

i was wondering, if you stay stopped for a bit does it ever come back down to normal?

zcarron

No it stays at high idle anytime I am stopped.When I first stop it will be normal then goes up high.

Sounds like possibly a vaccume leak.

Again....

oh ok, the reason i ask is because my idle would go up as i was comming to a stop but eventually would go back to normal, come to find out the BCDD was outa wack and needed to be turned up

zcarron

I blocked off the vacuum line to the BCDD and the idle went back to normal.So I guess it was the problem after all.
