Also, to add, when on idle the rpm's fluctuate which contributes to the car shakes. I had coils/plugs, oils, belts changed. The only thing left is camshaft tensioner and sensor, but before I can touch those I want to rule out whats wrong with with the lambda sensor. I have read that it might be MAF sensor giving wrong ratios of air which knocks out the oxygen sensor, although I am not sure. Any help is appreciated.

Check data on a scanner with a live data feed, you can watch all sensors and see if they are working with in range, start here.A factory hard cover manual or on line manual should give the correct parameters for all sensors.
