the alternator is sucking more power from your engine unless its going up very significantly then I have no idea
rpm goes up and does not change gear below 60
Check your regulator. It controls voltage to the headlight. If it is defective you will get way more than 6 volts to the headlight above 3000 rpm.
Rpm stands for revolutions per minute. This is talking about the revolutions the crankshaft goes per minute. The faster you go to more revoultions that are accomplished. Therefore the faster you go, the rpm goes up. And as you slow down it goes down.
what is wrong with my rpm it goes up and down
it needs a tune up
iac is bad need to be replace
RPM means Revolutions Per Minute. This measures the amount of times the crank shaft goes around in one minute.
Air Mass Sensor circuit, you probably knocked a wire off ...Engine goes into a (Safe) mode when there is a malfunction in this circuit and will not let it go over 2000 RPM.....
have to rave my truck up to 3&4 thousand RPM before it goes in to revers
idler pulley.
If the rest of the Transmission continues to function, then result is that the engine RPM's will be higher when cruising than is normal. Overdrive reduces the RPM's at the speed where it engages.
Your tachometer is broken.
