Hey, guys. I got an 03 Black GT coupe with 12,500 miles on it. poweradders are UPR Cold air- intake with fenderwell mount filter, a UPR 3.5" O/R X-Pipe, and Flow 40's. Lately when I get ready to leave, I let my car warm up, then take off. Well, if I stop somewheres and shut it off, then come back 5-45 minutes later, it will never crank up on the first try, no matter how long I hold on the key. It will start the second time though. I don't understand. Why does it do this? Should I take it to the dealer on a warranty issue? Any advice would be greatly appreciated.
