Hello Gents,

I have been searching the site to no avail.
My friend just bought a 1995 E320. It failed the emission test. We read the code off the flashing LED under the hood and found out that there is a problem with the O2 sensor. I am not sure if O2 sesnor would cause emission test failure so I wanted to check the fuel mixture on it. On my 86 300E I could read the duty cycle have an idea of the mixture rate. It can then be adjsuted by a hex key on top of te KE fue injection system.

Can you please let me know what type of fuel injection system is installed on 95 E320 and whether there are similiar ways as in 86 300E to measure/adjust the fuel/air mixture ratio? Also I know that Ford Mustang O2 sensor fits my 300E. Is there a cheaper car whose O2 sensor fits 95 E320?

Thanks in advance.
