After a HG change, my car has had a stutter when throttle opened wide at idle (stationary), when driven it doesn't pull like it should, so far I have tried the following;
1) Timing - all fine
2) New AFM - no change
3) checked all Intercooler pipework is connected
Anyone any ideas, it looks to me like a fuelling issue but not sure what to try. All was running fine ahead of the HG change...
Dirty injectors maybe?
Any ideas welcome as I'm getting frustrated with not having her on the road....
Thanks,
Topp
