Hey guys/girls. I have go a problem with my 95 sti wrx. I will be driving and put my foot down on the gas and it doesn't boost hard till it gets the revs up, it kind of surges a lil bit then just comes on real strong. It did it a few weeks ago then went away, and now it is back again.
Any ideas on what this could be? I was thinking maybe the coils or sparkplugs, but I have had them replaced no to many kms ago.
