my engines doesn't have any power i took off the manifold to paint it and now the car runs weird? when i first cracked it up it didnt. so i switched the fuel injector lines fired right up. but the idle is still very erratic? i checked the vacum lines and fuel lines grounds cooling lines and connections all good but it does the same? i test drove it and when i floored it when no where? could it be that one if the pistons isn't firing? thanks guys?
