RPM goes up and down

[bussybee]

when stuck in traffic the RMP goes up and down for no apparent reason

i am into a habit of pulling up the handbreak so i have not got into trouble yet but before i do i need to fix this problem.

Get your car tune up, its pretty normal for it to loose the idle range after sometime.

Professional tune up will fix this in a flash.

I had the same problem before, but the problem is more prominent, when I drove to upside ramp.

Please tune up and replace your tranmission oil. I hope it will gone.

If it will not resolved, it could lead to a prolem of gear box.
