motorsport injectors

hey guys I have 42 lb motorsport injectors and they have about 15000 miles on them and they are getting really noisy (sounds like loose rockers but its the injectors) also the car is starting to load up a little on initial startups and idle fast when I come to a stop until I rev it then it'll drop back down.
Anyone experienced similar problems? Can i have these rebuilt? if not what is the best injector to go with cause I wont buy these again. thanks,

Actually I've experienced that from a Ford injector...a set of 42 pounders as well. The ones we install started making noise from a fresh start..so we sent them back to Summit, and they sent us new ones eliminating the problem..could be just a bad batch of 42's. The car had the same symtoms as yours...we even got them professionally cleaned, and still no luck. Sorry to hear about your problem.

Wonder if it's the higher PSI fuel system that GM uses? Those 42#s are now kike 45+ if you're running stock PSI.

The noise was not like a rocker noise, it sounds like an electrical short..like a live wire..I really can't explain it, but it sounds like a humm....

injectors

yea I have stock fuel pressure. my noise is a real loud tick if you put a screwdriver on the injectors you hear thats where its coming from. It was worse today wanting to idle at 1500-1800 rpms at stops, and almost didn't start till I held it to the floor to shut the fuel off once. anyone have ideas about rebuilds or other injectors I could buy?
