Mixture adjustment on LH injection system-Is it possible?
My '92 400E is running a bit on the rich side, smells like rotten eggs at times, but not all the times and I was wondering if it is possible to manually adjust the mixture as its possible on the KE/CIS injection system (with a 3mm T-wrench). I replaced the oxygen sensor recently and am now looking at other possible problems with the injection system. I need to get the car up to CA emmissions specs. Any suggestions?
Thanks in advance,
