Hey guys and gals... if there are any,
If you have or had a Z5, please post in this tread:
1. An unstable idle. What I mean by that, is that you rev the engine, the rpm's increase.... then decrease to the point that it goes below its idle rpm.... then it comes back up and stabilizes back to normal. Another example would be you're crusing on the highway, head on the offramp, and instead of downshifting you push the clutch in and the brakes, and come to a stop in neutral... and the same thing happens, rpms dip below the idle rpm, then increase, then stabilize
2. A misfire. What i mean by that is if you either have a check engine code for a misfire in ANY cylinder, or if you feel the car vibrating at idle. The idle vibrating could be lots of things, but the vibration that I am referring to can be known by going to the tailpipe when the car is idling, and feeling the exhaust flow... what you're feeling for is whether or not it has an irregular pulse. It may be hard for you to understand what i mean, but these two videos should clear it up for you. Both of them are of me revving my Z5... one at the engine, and one at the exhaust. Watch the beginning of each video, and turn up the volume, and listen and watch carefully... you'll clearly hear the misfire... chug chug chug chug chug..... and then i rev the **** out of it.... then you could hear the rpm's drop below the idle, and pick back up....
So when you post in the thread, if you could please include this information:
1. The year of your car
2. Roughly how many kilometers/miles on the engine
3. If you have any of these 2 problems. If your Z5 is running fine, then you need not answer any of the other questions
4. If you do have a problem, tell me whether you have problem 1 or 2 or both
I know that there is a handful of Z5's out there exibiting this problem, there have been many many posts about "my idle sucks" or "i got a misfire" or things like that...
My intentions are simple, I have a feeling there is some sort of trend going on here, and I think if we could all provide enough information, we can all trouble shoot these problems and figure out what is going on. But before we even try to start that, i'd like to know how many people actually suffer from one of these 2 problems.
Thanks a lot guys
