94 e320 idle problem
My 94 e320 has idle issues. When it is first started in the morning car runs fine but when it warms up the idle flunctuates from 500-900rpm. When the check engine light came on I had the code checked and it was o2 sensor. Replaced it no check engine light but car still idles like crap any help is greatly apriciated my felow mg owners.

Sounds like a bad mass-air-flow sensor. It probably has been given warnings every now-and-then like the idle temporarily dropping below normal before adjusting itself or engine dropping rpm inbetween gears when the transmission upshifts. If it's the MAF, it's a simple fix. One way to test this is to disconnect the sensor and see if it works without the fluctuation. If it's the culprit (of which I am sure, do yourself the favour and purchase a new one). If you decide to clean it, it should for the interim as you prepare for a new one.
