My 1990 mazda familia astina e-bg6p lags when i'm driving, it seems fine when i first start it but a few minutes into driving it jumps, kind of like not enough fuel is getting through but, the radiator fan switch was broken, i relplaced that and it seemed to fix the problem for 2 or so days, but now the problem is back, any ideas what this could be?

I would recommend that you start by checking fuel pump pressure. For directions, go to our homepage under the DIY section for both a video and directions. make sure the pump is producing pressure that is within the manufacturer's specs.
