Sudden power surge
This morning I started the 2008 2.4 Puma and began to take off. Suddenly there was a power surge and she shot forward. Luckily I was in my drive and not behind someone! Has'nt done it since.
She was in to the maindealer recently for injector seals to be changed and a replacement EGR valve amongst other work. I'm not saying this has anything to do with the power surge. The dealer did say that she had cut out on them while iidling (which never happened to me). Is the power surge and rough idling indicative of the VCV ?
She does sound different with the new EGR and injector seals. All fluids and filters were also done so I don't suspect a blocked filter. 1982 88" 2.25 diesel

I had the same, new VCV cured the rough idling and surging.

I sometimes also have this effect wehen taking off and lift right foot, it's always the same specific situation, extremely difficult to describe. I trace it back to the anti stall function. But mine doesn't shoot forward Smile

I could not run the pilot correction after changing the VCV on a 2.4.

EDIT

I would like to know the effects of not doing the mentioned procedure.

Really not necessary. Mine have the VCV change years ago, and we didn't do the pilot correction.
No significant issues or noticeable problems with that.
