just replaced erry sensor on the motor,plug wires good,new o2 sensors,vacuum lines good,brand new distrubuter the only thing i havent replaced is the ecu and the maf sensor.when u unplug the maf sensor i heard if its bad then the car should run good when unpluged,but when u unplug it it just runs the same.so i dont know if thats bad but i think the computer could be bad,i dont know anything else to try.does anybody know where to get a cheap new computer for the car?junkyards,dealers,autopart stores, or friends that might have one.the car runs alot better than when i got it.all its doing now is idleing up and down and i cant figure it out,help?thanks
