So i got my eclipse gst about 2 weeks ago and fixed it up, but the heat sensor was bad and so was the battery so we charged the bat. and replace the sensor, everything works fine now exept for once problem...IT STILL GOES INTO LIMP MODE! a mechanic said the muffler was clogged, but thats bs, cuz i could get to higher speed slowely, but when i try to accelerate fast it stops me around 3k rpm. check engine light is also on. is there a way to get it out of limp mode?

 

go to autozone or a place like that and get the code diagnosed.
