So out of the blue a couple of weeks ago, my 06 GT with a JLTII CAI + Brenspeed tune just died pulling out of a parking spot. Just stumbled a bit, then died. Tried starting it and it acted like a car that was flooded. Would crank the motor, trip like it wanted to start, then would just die. Repeat.

Had it towed to the dealer. They checked everything and found that the battery was in really bad shape and said that it wasn't turning the motor fast enough to get it to start and was just dumping fuel into the cylinders. Whatever. They said that it spit out a bunch of fuel when it started after a new battery was put in.

So it was running fine all last week, then on Saturday I went to start it up and it did the same thing. Acted like it was trying to start, stumbled for a few seconds and died. I didn't have time to screw with it then, so I took my truck. Fast forward to Sunday. I put a meter on the battery to make sure that it still had a good charge and it read 12.47 volts. Battery good. Just for poops and giggles I tried to start it and it started right up, and has been running fine ever since.

So I suspect that something else is going on other than the battery (duh). I don't think the JLTII or Brenspeed tune has anything to do with it as I've been running that for well over a year now. I know the filter needs to be cleaned, but I don't think that would do it.

So anyone have any ideas?

Thanks in advance...
