idle riding high and wont come down..

[xwill112x]

i need to work on my ICV as well...

but i still need to get my motor put back together before i start a new project :cool:

I just replaced it because of the code and its still showing 1222 even though the car is running better.

When I got this code, we changed all of the hoses, but nothing seemed to work.  It turned out to be a head gasket and a cracked head for me.  Hopefully you do not have this problem...

yea lets hope this isnt my problem.. with only 150k she's still pulling pretty hard.

Okay so get this.. I did like cobra suggested took the icv off and cleaned with electrical cleaner and let it sat and then tapped and repeated. I put everything back together and car starts up fine. i back out of my drive and take off down the street and at the first stop sign when i pushed in the clutch the car just completely stalled out. (now im starting to get a little pissed). I take off and make a few more stops and at each one the car stalled when the clutch was engaged.

I get home turn the car off, go eat, go back out to the car to take it out again and its fine (a little rough idle on cold start along with the ce light that only comes on when idling) and its been that way ever since.

Could the icv be shot and sticking. im really baffled with this thing. anyone in nj that can take a look at it?

Check the large vaccum hose on the driver's side below the air intake.  Mine had the same problem and stalled out on me.  It may have come undone.  Check, u never know.

Warm the engine up, then shut it off, disconnect the ICV connector and start the engine back up, still doing it?

worn AFM spring will throw 1222 ... I ajusted the tension on the door flap in the black box and car has not given me 1222 since( Only move the dial clockwise 5 notches max!)

I just went out and looked over everything and i noticed that the pressure regulator (#6)http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=13_0308&hg=13&fg=15
has a nozzle on it that I left uncovered and I wasn't sure what I should do with it.. should I use a small hose and just put a screw in it or does this have to be hooked up to something? I think this may just be the answer to my problems.

[roundel318]

Hook it up
I took a look where mine goes and it seems to go under the intake / throttle body, its dark out at the moment so I cannot see exactly where it goes.
This should be hooked up by all means!

The fuel pressure regulator has to be hooked up the the throttle body with a vacuum hose in order to function. Without it the engine is getting way too much fuel at and near idle. Don't put a screw in it.

After i did my thottlebody heater delete i forgot to remove #7 and it was causing alot of noise under my hood.. TOTALLY OT had to add it though

[tjts1]

I don't see it in the real oem drawing. In this pic, the hose running to the side of the TB in the red circle. Huge pain in the ass to get to.

[nofear3544]

Okay, I hooked up that hose and once again cleared the cel. It wasnt bad hooking it up, just used a pair of needle nose pliers.

After clearing the cel, I took it on the highway and the light came back on but only when the gas pedal was kept in the same place for a minute or so doing over 40 mph. When the cel would come on i would give the car more gas or take my foot of the pedal the light would disappear. It was only when the speed was consistent that the light would stay on. I do feel like the car is using more gas than usual though. I think im getting around 26-28 on the highway which isnt the best.

I dont know what else I could replace. I did order new plugs and wires but I dont think that will make that much of an improvement.

[roundel318]

Did you use a used O2 sensor?

[nofear3544]

no but i did purchase a cheap one on rmeuropean.com and I had to rewire it to fit. it looked the same as the stock O2 so i figured it would work, it just had a different plug. I do think im gonna purchase a new one and see what happens.
