Thank you all for the suggestions. Been away and didn't get a chance to drive the car until this weekend.

I am thinking it is the injectors as well. At idle when the cylinders are cycling I can feel the hiccup.

To make things a bit more complicated, pulled over at a gas station and then car would not start, no crank nothing. After 5 minutes or so it reluctantly fired up. Since then this has happened a few times. Any ideas on that?

Thanks
