Yes replace the fuel filter. Might as well, its cheap.
I know ppl are saying replace the FPR, but I say attack the problems that the system itself (the ECU, the codes) are telling you is the problem. You will still have the O2 sensors throwing codes anyways, even if the FPR is replaced most likely.
Move on then to the FPR, as many have said. And their experience is far greater than mine.

As far as ABS? Dont bother. Pull the ABS dashlight out. Not worth fixing and not worth having.
