Based on your description, it sounds like it could be fuel related. Have you checked fuel pressure? Also, have you ever noticed any black or dark gray smoke from the exhaust?
Is the check engine light staying on? If so, have you checked for diagnostic trouble codes? If you have, let me know what they are. Also, if your scan tool has live data, let me know what the short-term fuel trims are.
I will watch for your reply.
