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
