have an 05 that when i used to crank it it would start right up. now sometimes when i crank it i have to crank little longer than normal and you get a little cough through exhaust then runs fine. it has almost 64k on it and hasnt had any problems . any ideas??

 

Batteries could be getting weak and causing it to turn over slower. I know my batteries are starting to show signs and when it cold and the grid heater draws some juice out mine will do the same thing. It's happened two or three times now this winter.
