| I have an 04 since new. Within the 1st year it developed a miss. Dealer replaced the injector module. It ran great for another year when the miss reappeared. This time it was a wire to the #2 injector rubbed thru and shorting out. I suspect that was the main problem all along and not the module at all. I did not consider this a problem at all since it was covered by warranty and the dealer was able to fix without much hassle.
My Duramax has ran totally problem free since the shorted wire. |
