My IAC valve is clean now. Gonna see how it does tomorrow when I get to campus when the engine is hot.
Xr, you should get rid of that buick, its nothing but trouble, and even worse you dont know half of what's wrong with it, i say just pass it on to someone else and let them deal with it and try to move up in reliability with whatever money you can sell it for
Thing is, my mom wants me to keep it around so my brother can have it when I move on to another car. I also can't get a car loan because I have no credit and I'm not even working enough to be able make payments anyway.
Hopefully cleaning the IAC will work. Someone on a Buick forum suggested I clean or replace it. When it was taken off, the valve was absolutely filthy as well as the socket where it plugs in, so my dad and I got it literally shiny clean.
