Help please. On the road. Stalled.
Folks; We are on our way home with our newly purchased '98 540i, on route home from the purchase site. We are currently in Richmond and en route home to Carroll County Maryland. The engine is stumbling badly. OBD codes included MAF Electronics, #7 cyl misfire and "various" misfires. I replaced the MAF in Richmond and the engine is still stumbling. I am only getting a single code now, #307 (cyl 7 misfire).
1) I cannot get my hands on a shop manual on the road (not from dealer or independent parts houses). I don't know which cylinder (near the FW I assume) is cyl 7. Possibilities? spark plug fouled from malfunctioning MAF? coil pack? Is there 1/cyl? or 1/every 2 cylinders? Suggestions?
2) I have a crank position sensor in hand, although I doubt this is the problem. Regardless; I would like to install it, but again don't know where it installs. Can anyone provide a description of how the CPS is installed?
Thanks for suggestions. We would like to get home tomorrow.
