Hi all,

I have a problem with my 1993 Ford Ranger. It stated about a week ago,
the engine would idle at a very high RPM (3000 or so), but it would
only do it sometimes. Also the engine would rev up to 3 or 4 thousand
RPM sometimes when i pushed in the clutch to change gears. Sometimes
it would fall when i put it in gear, sometimes it would fall if I
pushed in the gas. However, today really concerned me. Today while
driving my truck, i pushed in the clutch to change gears and the
engine quickly jumped up to 4000 RPM, then it fell to 2000, then back
to 4000, then down to 2000 then up to 4 again. Then I put it into gear
thinking that would make the problem go away, and instead my truck
began to accelerate without me pushing in the gas pedal. As you can
imagine this is very concerning.

Do you guys have any ideas as to what the problem may be, and how much
it might cost to have it fixed?

Thanks in advance for your responses.

Throttle valve sticking ?
