540 barely runs. Code 1222, "Lambda Control" ? Help!
Help all,
The '95 540 almost stranded my wife today. Ran very rough at freeway speed, little or no throttle response. "Check Engine" light on.
Did the stomp test: #1222 - "Lambda Control 1".
Drove it myself a few hours later, seemed fine, until I drove it for about 7-8 miles, then did the same thing again. Barely made it home!
Any ideas? Bentley's has -0- information on this. Do I need to get it into a shop, or is this something I can repair myself? Have a JC chip.
*ANY* help is greatly appreciated ! ! !
Thank you!
