bad break up. i got the car tuned my jeremy and it was running GREAT but i was running out of fuel up top...a week before i changed the pump it started to break up up top. i changed the filter, pump, and plugs. today we datalogged the car and im getting some knock retard in 2nd and 3rd between 4900 rpms and 5200 rpms just for a second and it goes away but the car doesnt run like it use too.....its running like crap up top. i doubt its the tune so i was wondering what else i should check....ill post up the datalogs tomorrow.
