Which sensors did you change s1's or s2's?

Looks like the engine is running lean on both banks. But why i don't know.

Have you done anything else recently?

All 4 sensors have been renewed. It's running fine but sometimes a slight hesitation under acceleration. Doesn't come on straight away after resetting but don't feel too happy about using it like this.

Thought I'd update. Took the car to MRC and discovered that a lambda was in the wrong bank! Strange cause all of them were ordered and changed one by one. However had my car carbon cleaned and remapped to stage 2. Spot on service by MRC, would highly recommend. Thanks for your help.

At least it's all fixed now man. Now to enjoy the weather and get her out and about and enjoy the map. It make a good difference?

Yeah it's a completely different car. Felt quick before the issue with the lambdas but goes well now. Was a great drive back from there. Wondering what to do next now!
