My car had never really started fast......
last week I had a problem with my EGR valve....basically my car had started to idle very rough, but would drive fine.....it would also start really poorly, as it would turn over a bunch of times before starting....after taking out the EGR valve and cleaning it(Soak in brake cleaner and then oil the shaft), and then resetting the computer(disconnect the neg battery terminal for 5 mins), the car starts up faster than it did new, and runs beautifull....my egr was completely seized in the open position.....car is only 1.5 yrs old.....it had been obviously going for a while, despite the fact it just got bad recently.......anyways, it was a pretty easy fix, with no money spent(had the brake cleaner already)......might be a soultion to your problem......1/2 hour fix......worth a shot, it worked for me by surprise....
