2006 a5 running like a bag of s***e

[John 89]

Hi wonder if any one can help i have a 2006 56 plate a5 with only 203,000 on the clock. Ive fitted a new camshaft and lifters with new bolts timing belt kit and water pump. It runs very well when it feels like it but other times it runs like a bag of spanner. Some times you start it and it just does not want to rev and other times it fine. I have ran a fault code scanner on it and nothing comes up any ideas? have also changed the tandem pump and black box of tricks that the vacum pipes connect to. I have another a5 which has been crashed that i can change any bits over from so any sugestions welcome. Engine code on both bxe

Injectors adjusted correctly?

forgot id done them yeah i followed the manual i fully adjusted them and then turned back 180 degrees

would replacement injectors cause a problem if they were fitted wrongly.

I ask because my vRS has recently had them replaced but the car sounds knackered.
