    I have to run now but can make a quick writeup later. Hope this helps!

    Thanks, looking forward do doing this myself!

    Well, I think i'm gonna push this car off a cliff. The problem is back. I tried switching solenoids, still back. Ran great all night last night, drove about 30 miles. This morning it drove great for 10 minutes, then it decided I shouldn't have any joy in life, and crapped out.

    I don't know what to do now, I offically am sick of this car.

    Shit.


    I am messing with my VANOS right now - I am almost convinced that it is my solenoid that is a piece of shit. Took it out and tested it, it works, but it's kind of slow in its action. Which for me, might prove it. Check my reasoning:

    My hesitation only happens from idle, and only happens when I take the clutch right out and go.

    It does NOT happen as much if I rev it up to about 1.5k and wait a second, then go.

    I feel that my VANOS solenoid is a little sluggish coming out.

    VANOS kicks in right above idle, right?

    So maybe when I'm revving it up, the solenoid comes out, and I'm good to go. But if I don't, then the solenoid is taking its sweet time and that's what the hesitation is. Make sense?

    Then again, sometimes it seems logic doesn't apply to these cars. Have you taken the solenoid off ever?

    Wish I could understand this TDC timing thing.. What exactly do you look at to determine this ?

    Changed all 6 coils

    Well, on my '92 i have no VANOS, so that couldn't have been my problem.

    I would get a fairly rough idle, with bogging around 1500 to 2500 rpm, and an
    occasional mild backfire... I changed the plugs and filters, still same.

    I took it to a bmw mechanic, and he suggested it was some of the coils.

    So I ordered 6 new coils for peace of mind, and voila, all the hesitation
    and bogging and backfiring is gone! Woohoo, its like a new car.

    Just wanted to share my experience.

    Cheers,
    Mitch

    Sorry, yes, I also replaced the O2 sensor a couple of weeks ago, but that brought no noticeable improvement...

    if it is mainly at 4000rpm, use single electrode plugs, gap them to 44-50 thou, and put in clean gas from a new station, drain all the old out, and put in 2 cups methyl hydrate in the tank when full, beat the car a lil on that tank, prob will go away... its ignition...

    My problem wasn't o2 sensors, but coil packs. I finally got an engine code and it was a misfire on cylinder #2. Repolacing the coil packs and plugs is the resolution. When I took my packs out, each one was "flashed". So I would look into that maybe in conjunction with some older o2's.

    On both sides of the coil you can see a white, almost burnt residue. That is the result of "flashing".

    Ok. Around the pack itself, is what I am referring to. It is visible on the entire circumference of the pack.

    Do you mean at the bottom of the tube (boot) or with the boot off?

    Sorry to be a pain in the ass!

    The coil pack itself, not the "tube" that the plug caps onto. Basically, with the cover off and the coils in place, you can visually see on the sides that they are "flashed" or not. Then obviously, when you take them out and inspect them more, it is more apparent on the round top part itself.

    okay i have this problem too. But mines a 92 so it doesn't have vanos, i noticed almost everyone in here has vanos, i read every single post and have come up with 2 solutions, coils, or o2 sensor. BUT before i spend this kind of money i want to know which to start with. here are my symptoms..

    the car will sometimes accelerate slowely, it'll just bog down after i slow down or stop and then when i try to accelerate it'll bog. It doesn't happen all the time, it'll happens when it's cold but more often when it's hot outside. It's annoying sometimes i'll be needing to make a quick turn across lanes and it'll bog on me. It idols fine, never had a problem with the idol. Also when i'm accelerating hard on the freeway, from about 60 to 100 or so it'll bog at about 5500rpms for just a split second then it'll just keep climbing to 7400 then shift like normal. Also when it bogs it'll sometimes backfire through my intake. It's not backfiring from the exhaust, but i'll hear a loud pop come from my intake. also i don't ever have any check engine lights or anything. the car does run rich.. ALL THE TIME, but i've been told thats because of my chip. I've removed my chip and noticed no difference so it's not the chip.

    mods...
    -cold air intake
    -dinan gen1 catback
    -dinan ecu chip
    -dinan auto chip

    I had this problem. It came up as an error 83 on the diagnostics which is the crank shaft sensor. I replaced it, about £60, never had the propblem again.

    A buddy of mines 318ti had a problem with accelerating and just getting up to speed. We checked a bunch of stuff explained here in these many pages of info, but im not going to read through all of them. One thing people don't check is the catalytic converter. That was the problem on this 318ti and it regained its healthy power and acceleration again once we changed it. Im not sure if anyone else has had this problem, but its just another thing to check if you've tried everything else.

    i have your problem. i hesitate all the time but its only really noticeable at freeway speeds and when hot out. ill be accelerating on freeway it will jump rpms and then go right back down accelerating doing this every 2 seconds

    If the RPMs are jumping and you're not going anywhere, you need a new clutch...

    Just thought I would bump this to see if anyone's made any progress.

    I will be replacing my VANOS solenoid sometime soon, then if that's not it, coils. Who knows.
