I did a little searching and really didn't find anything except that bad gas will kill them quickly, but ive had 3 injectors go out on me in 6 months and i have 105k. What would cause them to die to quickly?
I dont use bad gasoline either its always 93 Octane Shell or Hess only

 

It's really odd that you keep going through injectors, especially since you use high octane gas only. They tend to fail if they get gummed up, but I don't see why they would be unless maybe your running lean or rich? I'm not 100% sure on that though (someone correct me if I'm wrong).

Every oil change you should put some SeaFoam in your gas to clean out the injectors and keep them clean.

 

Im wondering if the electrical wires are corroded or the contact points jus need to be cleaned. I mean, mechanically they are rather simple, and shouldnt be failing that rapidly. They jus need an electrical signal for correct firing timing. Im wondering if Fuel Injection Distributor (not really sure what its called) is malfunctioning instead

 

How are they failing?

Leaking (hanging open), or dead (not injecting)? Could be bad harness connectors. Check the terminals in the harness and use dielectric grease.

 

I heard sometime before that floring the car frequently damage the injectors (do you ?)..just my 2 cents

 

well i used an ohm meter to test them. one tested out at 16 ohms so i replaced it and i had another that didnt even measure so i changed that one...i have three spare injectors now just in case lol

 

BAD GAS . . . Trash and or water in fuel . . . . CLOGGING from cheap gas
