I was driving my 97 STS 4.6 L and when I parked left it idling, when i got back in car, i put it in reverse started too drive, then it stalled... started it back up drove it fine for a little time then when im on the freeway with cruise control set the cruise control just shut off, car sputters, check engine light comes on...now I got all the codes for each injector PCM 0201 through 0208, P0603, P1602, P1626, P1654, P0371, P0377, is it the injectors or the IC because I checked the wires and in vacuum lines and everything seems to be in order how do I fix this problem

========================
codes are meaningless without their DEFINITIONS -
and no one has them all memorized -

go here for the best list of Cadillac code definitions -

also include whether the codes are C-Current or H-History -
