I was driving down the highway and all of a sudden my car just starts
slowing down I try hittin the gas more and nothin once I stopped it
stalled. Now it wont start unless I put the pedal to the floor and even
then it runs really rough then as soon as I let off it stalls. I have
replaced fuel pump, fuel filter, tps, computer, prom chip, idle air
control, fuel injector, new plugs, new wires, and tested O2 sensors, map
sensor, and egr valve. I'm getting spark and plenty of fuel, in fact I
think its running rich. Any ideas on what I should do next would help a
lot. thanks.
