This past weekend i changed the timing chain on my 98 z24.....due to water pump going out.....
now when we did this i put the time on "time" and put everything back together and when i started the car up
it had a very rough idle, rpm's jumping up and down but when you drive it the engine sounds good with no knocks
whatsoever, i checked for leaks and double checked the timing,looked for any water that might have gone in to the oiling system
i also changed the iac but nothing seems to work...so my question is what else can be done....or things that i might have too look into?

plugs wires etc, all of those good, even though you did the chain and the water pump it could be a fuel related issue just hazarding a guess here.

well spark plugs and boots have been switched out not too long ago and also the coil pack, and idk bout the fuel part cuz it was totally running perfectly fine

yeah you said perfectly fine when you were driving it, so something is causing it to idle rough sounds like it's time to do a scouting trip look for anything loose or popped off your vacuum lines all on.

do you any of them that can be possible

i don't, i was just guessing but i'm sure someone on here will chime in Good Luck sorry i couldn't be of more help.

off a tooth on your chain?

yea it was off by a tooth on the intake cam.
thanks for the replies i appreciate it
