History: My '86 300E developed a warm-start difficulty about year ago. The problem persisted despite changing the plugs, cap & rotor, wires and air filter.
About 1 month ago, I decided adjust the EHA per the instructions on this forum. I may have inadvertently turned the adjustment screw too far before realizing that my screwdriver was, in fact, seated in the screw head, and the screw turned with very little effort. Having lost my point of reference, I gave the screw a partial turn in the opposite direction to try to 'undo' my possible overcorrection.
After my attempt to adjust the EHA, my car sat for 1 month until last weekend, when I was able to charge the battery and start the car.
The car started just fine, but now has an uneven idle. The engine stutters severly until the RPMs exceed about 3K; then it smooths out. It's practically undriveable. Even when the car is warm, there is a pervasive gasolene odor in the exhaust... too rich?
Could this be a result of a misadjusted EHA? If so, which direction should I turn the adjustment screw to remedy the problem?
Thanks!
