We just bought a 93 Benz 300E recently, and the first e-test I took it in for it failed. HC: limit 54, reading around 150. NO: limit around 200, reading was in the 700's !

I swear, I put nothing else but a gallon of methanol in the tank, went for a retest the next day and passed.
HC: limit 54, reading 54
NO: limit around 200's, reading was in the 100's

This was this past weekend. I'll post up the failed and passed e-test when I get a chance.
