Last we I attempted to wash my engine compartment. After de-greasing and hosing down, I was having trouble keeping the engine running under load.

I poked around for awhile, and at one point I disconnected the sensor socket on air filter sensor and found it a bit corroded and still wet. A little contact cleaner, and re-seating the plug a couple of times clear up all problems. Oh, while I was doing this I used my hand to partially block the air intake hose (don't know why, just goofing around).

Anywho, after all this, my Lamda light is now on. Did I do something to set off some sensor elsewhere? Can I re-set the Lamda light?

Thanks
