OK, so this is what happened. I'm on my way back home on the highway and my gas light came on. No biggie, I get off and get some fuel (Premium) and 5 mins later, Service Engine Soon light pops up. Come to find out i threw a P0171 (Fuel System LEAN BANK 1) code. after some research using the "SEARCH" feature LOL i came to the conclusion i might have got some dirt in my injector.

All i have is a AAM spacer, topspeed catback and pop charger.

Now question is, what should i do? Should i drive it hard? Add cleaner? Or could it be a O2 sensor?

I checked for any intake leaks, went over and checked bolts blah blah blah.

The car isnt sputtering or hesitating and is running perfectly fine. Perfect idle and all.
And oh yea, my local mechanic turn the SES light off and i came back on an hour later.
Any more info would help. Thanks guys

Did you check to make sure the fuel cap is tight (clicking)?

No go. Opened and clicked closed. The light is still there. Unless it take time for the SES light to go away. hmmm

p0171 is bank 1 lean. i would listen to see if you hear any air leaks anywhere. if you have access to a smoke machine hook it up to the induction system and smoke check it to see where your leak is. i'd double check that aam spacer by spraying some brake clean around the spacer and listen for a change of idle

Without resetting/clearing the code, it will take a little while before it goes away - assume that re-tightening the cap fixed it problem.

Problem solved. Dont know what might of done it but this is what i did.

Checked intake tube and pop charger
Checked bolts on the spacer
Checked gas cap as per Daves advice
Drove the car hard for about 30-40 mins
Filled up with Sunoco Premium

Instantly when i turned the car on after fill up, light didnt come on.

I also heard from one of my customers at work, that he also had the same problem but alot worse. He had knock and hesitation in his truck getting fuel from the same gas station where i got my fuel that may have caused my issue.
