Car almost cuts out

[djtreble]

Hi gents, new to the world of the compact but not to BMW's (e36 318i and e36 325i in the past)

I have an issue that I'm battling to sort out.

The car battles to get to idle speed when the revs are dropping off (rev and release). It almost dies but then then goes to idle. It also dies when reversing on full lock and sometimes when you first start the car.

- I have sprayed carb cleaner around all pipes to hear for fluctuation in revs (leaks)
- I have just given the car a oil and air filter service and cleaned the spark plugs
- I have cleaned the AFM
- I have also cleaned the Idle Control Valve.

Any other ideas? I'd like to get this sorted out ASAP as my missus is moaning about how much it cuts out when she drives it.

The car seems to run perfectly otherwise

Thanks all
Dylan

How many miles or km since you change the upstream O2 sensor? Any Check Engine light? Why clean the plugs? please replace them, they are cheap and will elimate that as a issue. Check spark plug wires for cracks?

Is the car missing like a spark plug is not firing or is the idle not steady (idle up/down almost stalling)?

Is it a stick shift or automatic?

First thing in the morning buying new spark plugs.. mines a stick shift i want to maybe swap coils to see which one is misfiring (if at all it is a bad coil) but i dont have the cash yet ;( im getting a knock sensor #2 reading 1226 from the stomp test so im pretty sure it could be that..

When you pull the plugs look at them close and see if they all look the same? Does one look much different? If so that might be your mis-firing cylinder. Also I don't think knock sensors are active in the tune at idle but they sure will kill performance so get that fixed too.

Perhaps the ICV is bad?
