Since I've had the car it has had a rough idle. I was at a friend's earlier today and when I started the car, the check engine light would just flicker like there was no tomorrow. It would go away for a second or two when I floored it but would start flickering again. The first time I gave it so gas (when I backed up), a nice yet small cloud of black smoke came out of the exhaust. I've attached a video I took 5 minutes ago just so that you can hear the engine. I have the Bentley manual also so if you could point me to a specific page along with some instructions on what to attempt, that would be nice of you. The check engine line never appeared on me before and I've had the car for two weeks, driven it for about 650 miles since taking ownership.
If you listen carefully to the video, there's a small lag from the time I give it gas to the time it starts to rev. I attempted to simulate what happens when I just give the pedal a kick with the toes. Along with the lag, there's also a drop in rev's, like it was going to stall. The mic on my iPhone captures too much noise as it isn't as noisy when you're by the car but you can hear that the engine isn't running smooth and that it's missing somewhere. I checked the spark plugs and wires last weekend and they were all good.
Notice how in the interior video it is hard to start. It's always like that when it hasn't run for 30 minutes or more. You can also see how it got a small rev boost right after start up, didn't give it any gas...
ANY help would be appreciated.
Videos are in HD for better sound quality.
Thanks a lot.
PS. I was told that the fact that it is hard to start when cold could be that I need to clean the EGR valve and from what I have read around here the rough idle could be the ICV needing to be cleaned. Could someone point me to the pages related to those two parts in the Bentley manual because I obviously can't locate those. That or a picture with those two parts circled out.
Thanks again, from a new E30 owner and a noob at mechanics.
Update: It stalls on its own and I'd say that it is undrivable.
