Have you changed fuel injectors. My Buick century did this. Changed out couple bad and went away.

No injectors, but haven't checked rotor or cap. Will check them in the am.

Checked cap and rotor button they are good. Found fuel leak at filter. Put a new filter on not leaking there tho it started leaking at pump fitting

Well fixed the leak at pump and new filter started leaking at the seam.! That 2 defective made filters from microguard. Don't think I'll be buying any more of there stuff. Trying to seal up this leak. Still haven't figured out why it started this hesitation yet

Still no luck, out of ideas. Took it to a shop a week ago. They have not had any more luck than I did.
