after the 92 metro warms up, the car idles to high. Every once in a while, it will come down. But usually it stays up there. I think this might even be a reason I failed emmisions. The guy(inspector) kept trying to kick it down, but it continued to idle to high.
I pulled the little rubber plug (driver side) out under the air cleaner & tried to adjust that screw. It would idle higher, but the screw would not turn in the direction any further to bring the idle down. I'm not even sure if that is the problem.
I hear people mention tps switch's & pcv valves on other forums. I don't know what these are or where they are located, and if they can even be the problem.
Once again, I'd appeciate any input. I need help!!!! Thanks Guys for sharing your knowledge.
