Looking forward to watching this - where I am right now I can't unfortunately.
OT but it would be good if you found some time to get involved in the various COBB related discussions going on here. Alpina_B3_Lux

Where is episode one?
It's a great video and shot really well. However, how would you address the new find with injector coding and it's relation to misfires? Last edited by onesuperboi; 02-09-2012 at 12:13 PM.. |

That was a good video, shows everything very clearly.
Btw when it says cylinder 1 for example, is that the one closest to the front of the car or is it the one closest to the windshield? |

This video is very good but it misses the situation where an the injectors have gone bad or have been miscoded by an incompetent mechanic at the BMW dealership. There are a lot of engines with miscoded injectors, as it turns out. Here is how to fix this problem:
