Not sure if this was already asked and answered. Have you ruled out coil packs as being a cause? The 320i had a coil that got a bit weak and it would cause the engine to stutter from low speeds. It never had a misfire or idle issue, but the moment you set off from a rolling yield in 2nd or 3rd gear, it would stutter and bog down.

What about fuel pump/filter? Maybe worth having the fuel pressure tested.

Saw that the coil packs were corroded on the outside at the suppressor didn't know if that could be a factor. Must still check fuel pressure

Funny that Phillip posted the above.

Found the following error codes on the car after I experienced flat spots.

Fuel Trim Bank 1 Control Limit OBDII P0170
Fuel Trim Bank 2 Control Limit OBDII P0173

Found a tear in the exact same spot as Phillip.

Scary part is that the boot isnt that old and its OEM....

Sorry for derailing!!

This is at least one nice thing about the R46s - there's always someone out there that has experienced the same problems that you have with yours, just a matter of finding their thread! LOL

Found on you tube a good way to check for vacuum leaks. They use a small smoke machine works like a dream. Burn mineral oil and blow smoke into vacuum system and you can see where it peels out. Absolutely marvelous. Google smoke machine for vacuum testing

went to have a look at the lower intake on the car this morning... and found its torn in the same place as the pics posted earlier. i've removed the filter housing, maf etc...but i cant figure a way to get to the two hose clamps to get the boot off. how did you guys do it? i cant even get my hand near that area

if i remove the DISA.. will there be more space to get them?

Will help if the Disa removed. I used a 1/4 inch ....6mm socket with knuckle and extension easier than a screw driver

To do this job you do need a good mini socket set as well as a set of torx bits. That lower intake boot is tricky to get off simply due to the location and orientation of the hose clamps. This is why I removed the DME compartment cover and there is some or other harness of hose that is held onto the intake with a metal bracket - removing this also just adds some extra space along with the DISA being out.

thanks for the tips guys. i gave up after about an hour..but will try again this week sometime. i reckon it might be easier to just cut off the old boot and the hose clamp if replacing with new parts

Just bear in mind that the new intake boot does not include new clamps, so if you destroy the existing clamps you will have to get new ones separately.

If you have a small socket set like this, then you should be able to get those clamps off fine, unless they have literally been put on such that it is impossible to get off. They are normally facing down, so when you refit them, have them facing up so that you can access them from above, much easier. You may need a small 6 mm spanner to make life easier though, that was the only way I was able to get those loose in their original position.
