Rpm's bouncing
 

Since I bought the car it's been doing this. It's not bad and you can't really tell but the rpm bounces around a little when it's right on the line at 1500 rpm. It doesn't bother me so it's no big deal if I can't fix it I just wanted to know why :thumbsup: once the needle is idling on 1500 it will bounce from there to 1700 at the most and then back down.

Any codes? What engine? Seem to remember having a cam position solenoid issue causing that surge on a v6 impala at the shop, not too long ago.

Check engine light isnt on and it doesn't bother me but im not sure about any codes
