k12 timing chain issue? help

[Kam May]

So the issues are, when slowing down for junctions etc the car turns off, feels very unresponsive when speeding up, and feels like the car shakes a lot when moving slow in 1st or 2nd gear. So i had a diagnostics done and that pointed out that i needed a new lambda sensor, cam sensor, crankshaft sensor. Got that work done to it and it worked fine, felt like a new car, for a few days...then it stated turning off again when decelerating etc. So i took it to Nissan and was told it might be the timing chain and would cost me £1300 with them. I assume i can get it done a lot cheaper at my local garage so will be taking it to them today to see what they have to say, but wanted more peoples opinions on the issue and the possible fixes. It's a 05 plate 1.0 k12.
Thank you
