Hey everyone I'm in need of some help. I recently purchased a 2001 525i Touring in Blue Water metallic. Couldn't be happier car is in great shape. But I got it for cheap with a cylinder 2 misfire. Brought it home. Did plugs, noticed oil in spark plug wells, so I did valve cover gasket/tube seals, still not fixed. So I did coil packs, then camshaft position sensor, and finally I did fuel injectors. STILL a misfire in cylinder 2. Where do I go now? Anyone wanna buy a wagon? Lol [IMG][/IMG]

Did you try cleaning the MAF?

Have you done a compression and or leak-down test

+1 compression test. Easy and tells a lot. Could have a bad broken valve or stuck piston ring.
