Hi
I have a 2003 Sonata with 45k miles on it. When I go to start it recently it does start, but it takes a few seconds longer then normal.

I tried STP fuel injection cleaner. Has anyone had this problem and can recommend a fix. I wouldn't think that the plugs need changing at 45k miles, but maybe?

Any help would be great.

I would check your battery first.....start with the small cheap parts then work your way up. Doing maintenence to a car a little sooner than needed could never hurt anything.
