AFTER THE NEW FUEL PUMP ...... 900

Well we have replaced the fuel pump in this '93 940 wgn. and it is running..BUT..I have some chatter around the 2000-2500 rpm range.
I have strated using 93 octane fuel and some sea-foam but no change.
We are going to try a new Throttle Body Gasket and see if there is a change for the good.....
I do have some code's from the "A"-2 port of 231 and 122....
what else can these issue's come from......maybe "knock-sensor?
