Problem still there... ren engine code again and it give a 55 wich is "no problem" code i believe. Im thinking its one of 4 things... fuel pump, because its making weird noices sometimes, bad fuel injectors, bad distributor, somehow getting bad spark (any advice on this?) Knocking sensor, i dont even know where it is and i dont have a manual and does anyone know how much those are? ir how do i know if its bad and how could that be the problem of my car hesitating, jerking at cruising speeds, loosing power at certain rpm levels, and feel like i step on the gas and quickly let off while normally driving and sometimes at WOT.
