2002 no power can't get any speed

My 2002 exp was running good, then two days ago would not start. Got it running again and ran fine, then the next day lost all HP, could not get above 30 mph. I changed the fuel filter know the engine is making noise? The plugs were canged back in January. Any one have this problem could it be some bad coils?:banghead:

do you have a check engine light? if so find out what the code(s) are and go from there
good luck

How do you get the code without the reader. I remember in the old days you could jumper between pins, can you still do this?

buy yourself a universal code reader, best investment you can do for the new cars and trucks

Or go to Autozone or Pep Boys and have them read the codes for you. They do it for free hoping to sell you some parts. Post the code numbers back and we can help more.
