I am aware you can clean injectors. Im sorta trying to diagnose a problem. You see, when the car is cold, and I start it, it ignites no problems, but if I dont tap the accelerator, it goes to die again. So I thought maybe the injectors weren't pumping fuel for that initial startup. Any suggestions as to what this might actually be?

I have a series 1 Non turbo R33. The car has done 163k and is getting to the point where I think the injectors need replacing. Any suggestions on what Injectors I should be looking at and what price ranges they're in. Open to anything, just need some suggestions.
