[8D]I recently had an intake vacumn leak repaired by dealer. At the time I mentioned that the car turned over 4 to 5 seconds before starting. They did a tuneup and replaced the plugs. Also a fuel filter replacement. The car continues to start poorly. I went back to the dealer and they checked it out and said it was a fuel quality issue but I only use top tier premium fuel. Can anyone tell me what might be causing the poor startup.

 

how old is your battery? and what are the amps/cold cranking amps?
