Ive noticed it the past couple of weeks. The car just does not seem as strong as it used to be. What do you think it is?? Hot summer heat, fuel filter? I've also noticed it does not crank up as fast it used to, it now has to spin over several times instead of the usual 2 times. Anyone got any ideas??

 

Have your injectors cleaned either on the rail or off. However, off the rail can be flow checked as well.
