well my 1994 E320's Check Engine light came on and I used to have a set of
steps to follow to check my fault codes, but I'll be darned if I can find it.
I have a list of the codes, but I don't know how to check/clear/check again the
codes under the hood.
I know I have to have the engine on, but I don't know how to do the rest
This time I SWEAR I'll put it in a doc on my hard drive and I'll never lose it
