car threw a CEL light today. first it rattled then CEL started to blink. i took out the coilpacks and spark plugs out they seem ok. i am not 100 percent sure they arent the problem. checked dv that was ok. reset the ecu started problem still existed. maybe fuel pump?
i am gonna drive to autozone tommrow to see what code it will say for CEL, anyone had this problem before??

 

start car, remove one coil pack at a time, if nothing changes on one , that's the culprit, had the same problem and it was a coilpack, if so replace all 4

 

if that doesnt work it might be the spiral control mod aka spark controll mod
