The fuel injectors can fail and cause drivability problems. Often there is no Check Engine light and the failures can be caused by corrosion of the connector, clogging beyond the point of cleaning, and/or internal failures.

    I'm not sure why or how this is happening, but my 2005 frontier has had a number of backfires and clunks in the front engine compartment. It has been so loud and abrupt I stopped to get out and look under hood for what broke or maybe something from under truck. When I found nothing I was a bit worried. My tuck is now in front of my house broke down. I have no idea of what the problem is and NOW I'm without a vehicle. I was hoping I could find some others that may have similar problems because this has become quiet a dilema. It not only has taken up any free time I do happen to have but I is now putting me behind on food, on bills, and rent. It started to affect my work as well. I could really use some suggestions on what my next move should be
