Ok guys here is my issue! And it started as soon as I swapped exhaust what could it be?

Car is stock other than Fast Intentions Catback ' well I never had an issue until I sold my exhaust and got the Tanabe mufflers put on and all the sudden couple days later the car shut off about 5 times after trying to start it. Very weird I tried again a couple day later and car was fine and I reset my battery and car was fine but dammit it died again and again I have to strt it and rev it up some times so it wouldn't die. Any ideas ? Keep in
Mind it only started after swapping exhaust but I doubt that would cause this! What could I look for or be worried about?

 

Your battery may be on its last legs. What year is your car? How many miles?

 

2008 w 45,000 miles^ that's what I'm thinking! Don't we have some battery issue?

 

Yeah I think you 2008 guys do.

Have a copy of the TSB ready, wait until it dies again then call Infiniti Roadside to tow it to the dealer.

 

Perfect thanks ! I'm gonna take it in w this TSB!
