Hi all!
I am getting a code 23 on my computer which is the Mixture control Solenoid, can someone tell me where this is on the TBI?
Thanks alot, still waiting for my haynes manual to get here. Darren

my book shows code 23 to be manifold air temp/intake air temp sensor. thats the one screwed into the side of the air cleaner, might make sure plug is tight

Hey thanks, I actually got that code name from a list of codes on the Yahoo Geo metro site? Maybe it was for the wrong year? I had just changed that part actually that you mentioned. I am curious what book are you using? I am still waiting on my Haynes.
Thanks for the quick response! Darren

PS also how does a person reset the codes?

Hey sure appreciate it, After I checked out my TPS and made a little adjustment I reset the codes, and now am getting a code 12. Any help with that one? Thanks

code 12 means everything is working right

I don't get it? I just fiddled around with a few things and originally had a code 23 and another code for the o2 sensor. It still idles rough I increased the idle screw a bit I think idle is around 1000 and that helped a bit, any thoughts?
It just had a full tune up with fuel filter,and wires. all the vacuum lines seem ok also and motor mounts look ok....
Thanks Darren

Hey I may have found the prob, I was poking around and next to the throttle lever on the driver side of the throttle body there was a rubber plug when I took it out it revealed a screw. I started backing it out and the roughness went away and idled smooth and the throttle increased a little. Seems ok is that an idle air screw?

[Crvett69]

yup, thats your idle air screw, supposed to use that to adjust the idle speed
