Not smooth

keyowne · 09-29-2015, 11:53 AM

Hey, I got a problem with the car and am not quite sure wht it is, first and second gear in low revs it is quite jerky, doesn't seem normal, am getting the bearing, suspension, etc checked this week, anyone any idea?

sounds like the muffler bearing

That's normal with this car, more so if your car is Not an automatic.

How low is low?

keyowne · 09-29-2015, 02:52 PM

from idle to 2k, very smooth after that. it makes driving a chore at low rpm as its so jerky. I thought could be the coils?

MightyMouseTech · 09-29-2015, 03:14 PM

Have to be smooth on the gas below 2k.

keyowne · 09-29-2015, 03:40 PM

I guess its a characteristic of the car then, I mite just keeps revs above 2k haha.

It's far worse as the suspension ages. But yeah, mines always been like that.

Is your car a manual ? Maybe the clutch is slipping?

Could be an ignition miss fire like bad coils or plugs. ? How old are your plugs? If older than ~45K miles(or 30K miles with a tune), you should replace them.

Do you have a code reader to check for thrown codes? That's your next best bet. You can buy a can/bus OBDII "dongle" and download an app to read the codes.

car is manual, no clutch slip, its more like the car is bouncing haha, i thought it could be traction or a misfire, throwing no codes though, plugs done 13k miles ago, still on original coil i think. I was told it could be suspension as well. Getting it checked tomorrow. Got a feeling it could be coils.
Seems to be a consensus that this is normal, bizarre.

well its fixed now, since i installed the cobb seems to of fixed it, it may be the change of fuel mapping or change of the throttle control to a linear throttle.
Its much better now, night and day to be honest, i think bmw should be thinking to make all there throttles response like this.
