I got the Lambda working, had to change the O2 sensor. I have noticed lately that the engine shakes slightly at idle, not a lot, but enough that when the doors are open I can see them shaking and at stop lights I feel the car shake. It's really annoying. I have replaced all of the vacuum seals/hoses/ o rings etc. Replaced the injectors and the ignition components are less that 1 year old. I have spark at all of the plugs and all have been gapped. Other than the shaky idle the car drives great.
