Besides, what causes RPMs to run high?
Clogged Air Filter But if this air filter is clogged or worn out, then there will be less clean air passing through it. This will cause the engine to idle rough. When your engine is idling rough and struggling, it often will rev at higher RPMs.
Secondly, what does it mean when your rpm goes up? Most likely you have a clogged (or failing) idle air control valve. Take it out, clean it, put it back… should solve the problem. There's a disconnect between the amount of air the computer thinks your engine is getting and the amount it's really getting, so it keeps trying to correct itself and almost dies/comes back.
Additionally, are high RPMs bad for your car?
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
What should your RPMs be at when driving?
Whenever possible, try to avoid hard or sudden acceleration to high speeds so that you prevent your engine from damage caused by over-revving. Step 4: Maintain fuel efficiency. For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.
