my 86 na did that too untill i gutted the cat and replaced the muffler, my has 240k on it and still runs strong as hell

hey yeah mine started to do that after a lil bit after i got the car.
to find out the probelm i took the ecu out of the lil compartment where
its stored on the passengers side and followed the diagnostic steps such as
idling it at 2k while it blinks lights at you. you get the code and look it up.
i did this and it said just to turn my idle speed control valve up so i did and i've had no problem since. heres the site where i looked it up if u were curious.

someone also told me that was the auto choke from a bad o2 sensor

ok thanks for the help i will try some of that and let u know ...thanks alot

that cliking noise could be in your steering an suspension . it kind of sounds like you have a contol arm(s) or bal joints problem .. with the car as old as it is i wouldnt doubt it ..

id say the idle adjustment or try just pulling it off and cleaning it with sensor safe cleaner also try the ecu coder
