another injector out

Took my truck in today for an injector problem. Was driving home this morning and my truck stumbled, shook, and started missing about 20 miles out. I had my cruise set on 62 and it was maintaining that, so went on in. My cel was on and Smarty Jr. read the codes, P020 and P2146. After clearing them 3 or 4 times, and then reoccurring, I cleared it and went in the house and called the dealer and got an appointment to bring it in. Later, I was able to drive it to the dealer without getting a cel and come home in a loaner. This is the 3rd time this has happened, the first, I drove it several months before it happened again. The second time required replacing #5 injector, last summer, and I'm going to have them replace the suspect injector this time, instead of driving it til I can't. I've been running Jr on the torque setting and not racing, not doing any jack rabbit starts, or doing any heavy towing. I do run heavy (11,700#) all the time. Will running the Jr in this situation cause me to loose injectors?
