  • HELP please NO POWER

    I have 1997 3.8, the car has no power , it could not spin the tires on ice(maybe)
    i changed the plugs, wires, all coils, new injectors, fuel filter, drained old gas out,
    i do get a misfire code
    car idles a little rough, but smooth out when you give it a little gas, and run smooth, rev it up and sounds good,
    the car just has no power what so ever
    any thought
    thanks

    How many miles? Clean the TB, air filter...depending on miles maybe the cat is clogged. But you'd prolly throw a code... Just trying to help!

          have you ever replaced the cat? It might be getting pretty clogged and causing you to have no power. It can also cause the random misfire code that you are getting

              you will have a code that gets tripped if you don't get an o2 sim or tune it out with HP tuners or mail order tune.

              Get under the car and hit the cat and see if you can hear anything rattling or loose in there. Also you don't have any wires crossed or on the wrong coil or anything do ya?

                  if your misfiring on one cylinder the car will idle a litte rough but then it will smooth out when you get to the higher RPM's... the problem being not only are you missing a cylinder fire but without that cylinder fire you are missing out on a LOT of hp... the cat would do it... but my car was just misfiring on cylinder 4 and i had to get new wires even though it just had new wires put on it not too long ago... once i changed that... she scoots now

                    i know whats wrong. we drive v6 camaors. haha. no power at all. but seriously, i think youve either got a cylinder not firing, or a clogged exhaust.

                      ok i had the coverter cut off today
                      a snail could go faster
                      still runs like crap
                      we double check firing order good
                      we pulled each spark plug wire off the coil, one at a time
                      then started the car, they all sparked like crazy

                      i will pull the plugs and recheck them, they have maybe 50 miles on them

                      any other thoughts
                      thanks
