Your 1984 fiero 2.5 2m4 is idleing around 2700 RPMs need troubleshooting you already replaced the oxygen sensor but its still idleing high?

It could either be a leaking vacuum line, EGR Valve or I believe its a idle position sensor on the throttle body. If you're looking for a vacuum leak, spray some WD-40 around the vacuum lines till the engine RPM increases. You'll know right away. If it is a vacuum leak it could also be where the intake manifold joins the engine. In either case it is not a good idea to drive it as it could ruin your engine.

Why wont your 85 fiero change gears when its started?

Could be a bunch of stuff, but some of the earlier Fieros had an issue with the shaft connected to clutch pedal bending which would cause the clutch to not fully disengage. When your car's not running you can shift gears all day without pushing in the clutch. Try that when your fiero's running and all you'll do is chew gears.
