I notice that there is a slight surge while acceleration but not to much. It's just annoying I've added fuel treatment with inj cleaner also have done a basic clean of the throttle body. And it's still there. Any help would be great thanks.

CHECK THE PLASTIC SNORKEL TO THE THROTTLEBODY FROM AIR FILTER. THAT PESKY HOSE TENDS TO BEND ON THE BOTTOM AND DOESN'T SEAT PROPERLY CAUSING AN "UNMETERED" AIR LEAK WHICH CAUSES THE IRREGULAR IDLE.
