I have run many tanks of gas through the car with the problem. A buddy who races dirt bikes said California has been putting in more ethanol and that may be it. I tried blending super unleaded with 100 octane unleaded. I think I picked up a few horsepower but didn't fix the idle problem. The race gas here is over $9 a gallon, ouch. Don't know if it threw any codes.

I used to build race engines over 20 years ago. My normal routine with something like this is change the spark plugs, clean the throttle bodies. Had a similar issue with my first Toyota Tundra, an independent said I needed a throttle position sensor, I cleaned everything out, new spark plugs and it was perfect.

The problem with dealership mechanics is flat rate, they get paid x hours for a job so there is incentive to rush it. If I have them clean the throttle bodies they will spray carb cleaner in with the motor running. That washes down the cylinder walls with the crap which isn't good for the engine.

If I want it done right I think I have to do it myself.

It's the gas. Even if your using 93-91 it's still the gas quality. I had the same problem from 93 from bp.

Are you sure it's not the Winter Blend gasoline which I think California uses?

Do it yourself, if techron hasn't helped.

Never feel like it wants to stall and will go away if I just let it do that for maybe 10 seconds. If I let the engine warm up for 30 seconds or so before driving off, this won't happen. Sean05/Richpuer, does your car need any fix or it runs perfectly fine as time go on. Thanks in advance.
I just moved from sunny Arizona to freezing ass cold NY and starting noticing this same problem...like the car has to warm up or something. This is my 6th BMW and I always like to clean the ICV but I usually will do this when I need to take the intake off...which is a hassle! I let it run for about a minute and it goes away and I have a smooth idle. I'm throwing no codes but I know it never used to do this in Arizona. I used to travel for work and within 1 year of owning the car I had only driven it three times for about a week at a time. Now I driving it everyday and its getting annoying. Is there anything I can do to clean this without removing it? I like my cars to run smooth and I've never had a BMW break down on me in 10 years of owning one. The inline 6 is one thing but this V8 is another....its a very tight squeeze in the engine bay! A quick fix it needed please

The M3 engines are calibrated to run 87 octane because idiots don't like to read the "Premium Unleaded Fuel Only", and they would complain their car ran like shit. So with the E9XX cars BMW calibrated for use with 87 to solve the "idiot" problem but still use the "Premium Unleaded Fuel Only" sticker. If you can afford a M3 you can afford to pay an extra $0.30 cents a gallon! So, yes...the gas shouldn't be a big deal. BMW recommends Shell because they use nitrogen that will keep your valves clean. Of course, no Shell where I live

I think we are talking about a different issue. Mine is as the OP stated, it only happens when driving off right after it starts and the engine jumps around a bit . My idle don't really jump around if I am not moving. I just let it run for like 20 seconds on start up before driving off and I don't experience the jumpy/jerky engine response. You might have a different issue with the ICV which seems to be a common thing on this engine. Hope you find the issue.

No. We are talking about the same issue. When I drive off the car kinda studders a bit when its getting going for about 20 seconds, then goes away. My idle doesn't jump around at idle either. I was just stating that I try to let the car warm up for a few secs before I take off because I hate when it studders. Like its starving for gas for 20 seconds. Trying to find out if theres a cleaner or system flush I can do to the intake or gas system to fix this.

Have you tried a couple of tanks with Techron concentrate plus? Maybe two tanks back-to-back? Cheap enough to give it a try, in the event it's not the ICV causing your issue.
