Why did you gut the catalytic convertor? Did you bother to check the 02 sensors before replacing them? You need to have a code scan done before you spend any money on this car replacing random parts. Gutting the cat could be part of your problem here, as well as a Federal crime punishable by up to a $10,000 fine.

gutting the cat, that's a smart thing to do.Start by replacing that(should only be around $1200.00) then throw more parts at...eventually you'll get the right one...

well judging by what you have done, i think you should take out the dash and remove the light for the check engine light:)

or just wait till it burns out. lol


Removing the dash light will not change your inspection result. You may not get the light to go out now because of the Catalytic gutting. I had similar problem on 98 Sephia. The rubber pleneum between the Mass Air Flow Sensor and the throttle body was ripped I put new sensor in and just taped up the plenum real good reset the code - light never came back on
