For the record ...
Update: I'm still tracking down a random error misfire sequence:
- Does the order of the misfire OBDII DTCs diagnostic trouble codes actually matter (
1)
To that end, I've started identifying & replacing all the vacuum hoses:
- How to locate all the vacuum hoses in the E39 engine bay (
1) & where to get those vacuum hoses (
1) & what sizes to get for all the M54 engine vacuum hoses (
1) & correcting the F-connector errors in the realoem diagrams (
1).
And, now that I know where the Schrader valve is, I borrowed the Autozone Actron CP 9920A fuel system tester:
- While replacing your spark plugs (
1), where can you find your E39 fuel system pressure test Schrader valve for the I6 (
1) and for the V8 (
1) (
2) (
3)
