couple problems

[turbosuzuki]

Ok guys truck is running rough again at a idle and sounds like it has a knock to it. Fresh oil new air filter also had #8 injector replaced along with the cps.
Truck doesnt smoke or stall or anything.
Also i just noticed when you first start it the interior lights are dim for about 10-15 seconds then everything gets bright
Any ideas guys? 02 cc with just a tymar intake and a 5" mbrp exhaust.

Thanks
