Hey guys whats up? I have a 1999 coupe I just got my back today from getting tuned. It has a gsr swap with integra type r internals, darton sleeves, Skunk2 cams and gears, a short ram intake, skunk pro series intake manifold, apexi world sport exhaust, 310cc injectors, hondata s300. So I jut got my car back today after having it tuned and having new motor mounts put in, and a new power steering pump. I drove it all night fine and about a half an hour before I went home I was driving about 25 on city streets and my speedometer just went crazy going up and down the lights on my dashboard started flickering and it is idling kind of rough now. Do you guys have any ideas what could be wrong?
