your foot...the more you push the gas pedal the higher the gauge goes, otherwise... a bad gauge (most expensive--and rare) or a bad SIGNAL to gauge(less expensive and common)...read up on the circuit testing..:) everyone should have a manual for their vehicle, and the local library should have a SHOP manual available in the reference section--make copies of the right info and read up..you'll be a pro in no time ...good luck:)

What causes the rpms to go up and down at idle?
I would look for a vacuum leak under the hood. If the check engine light is on have an auto parts store read the code(s). The code(s) will help you find the source of the problem.
