rpm goes up and down
Here is the problem i m having. civic MT, 2003, 42000 miles. I had my oil change (myself) about 400 miles ago. Now I starrted expericing this problem. 1: when i start my car it starts at around 1500 RPM, it was starting around 1250 RPM, ( i know you would say wearther effects, but trust me, its same) this is when i noticed something strange. Now after driving around, when its in netural, it stays around 1000 rpm and drops to around 750 rpm after 20-30 seconds(this wasnt the case, it was dropping to 750 rpm). and now when the engine fan kicks in, rpm goes a little bit high, around 1250 rpm, also when i turn the steering around. rpm goes high. Any idea whats causing this ? please advise.
Thanks
Thanks

My car "idles" at 1000 rpm when cruising on the freeway and the clutch pushed in. That's normal.
Its also normal to raise the idle rpm when you use items that take power, like fans, power steering...etc.

Yep, he's right. And when you turn, yes rpms go up

With the car running with nothing on....about 700 rpm. If you turn your headlights on, it'll go up a couple hundred rpm or so.
