hsve had my 99 boxster 2 weeks and CEL has come on. dealer knew as after 20 miles from pick up it came on and I brought it back. they cleared it and said when.they filled my tank.they may have left csr running and gave a false o2 sensor read. well it csme back 3 days later. autozone read it and it was a p1128 with a p1123 pending. i bought a reader, cleared it, and came back twice now as p1128, p1130 pending. it drives fine i think, but always scared when CEL light is on I do notice when in triptonic automatic mode seems sluggish between 2-3 gears, isnt that way in manual triptonic. also when in 5th and I gun it, it doesnt accelerate fast and will drop down to 3rd gear then climb back up. very noticeable jerk dropping back to 3rd as u can imagine. is this normal or because of CEL codes?

thoughts of what i need to do? dealr wont do anything.
