Hello im trying to figure out whats wrong with my 2002 ford taurus SE with a 3.0L V6. Ok so when i start the car and it runs idle its fine, but when i put it in gear and go to accelerate it sort of hesitates and doesnt go very fast. When i push the gas pedal hard the RPM's dont rise for a few seconds then if i dont let off it tries to kick in all at once and my car seems to jump. i brought it to auto zone and the codes that came up indicated that my right speed sensor was out, alternator input malfunction, catalic efficiency below threshold, 02 sensor, and that cylinders 2,3, and 4 were misfiring. i JUST replaced my spark plugs, wires, and coil pack today and the problem didnt change at all.
Im hoping someone has had this problem before and what i need to know is if its just one sensor throwing off all the others or what? i dont really have the money to do the process of elimination thing, so if youve had this problem or hav any advice for me at all please help!
