check plugs wires and mapp sensor, if you havent had wires and plugs changed in a while , you should do it anyway, but sometimes the wire will sit against the block and melt, causing the car to only run on several cylinders or even worse arc. check those out and get back to me

It wouldnt hurt to test the throttle position sensor either, for good measure, but do the fuel pressure first
