buy some NEW ones from the dealer or a trusted shop.

heres some threads that would help you out with the injector swaps if your going to tackle the task.

would the total new ones from industrial injection work, or how about just the nozzles from ddp or someone do the trick....and what exactly is the problem with the injectors.??

 

yes the ones from industrial injection would work, and they come with a one year warrenty too i believe. nozzles wont fix the injector, the body goes bad.

i dont know what goes wrong with them, theres hundreds of pages discussing what goes wrong and what the fix was over from 04.5 with the lly motor, but not everyone is 100% sure what kills them theres alot of opionions on what does the injector in.

 

also if you do put upgraded injectors get some guages first
