Nozzle spring problem

So my kjw p226 is having feeding problems. Unless the weather is very warm or I heat up the mags by the heater it will only shoot a bb every other shot. For example slide cycles bb shoots, next shot nothing, next shot bb so on and so on. I cleaned and relubed everything. I feel like it didn't use to do this. My nozzle return spring is a little bent. Could that be what's causing it?
