maybe you should take off some of the aftermarket parts off....or do a tune up and run on 91 gas..also try a new cat

 

your cats gone

 

yeah cat look likes its not working. also last resort, i say go get hondata s300 and tune it. thats what i did. ref doesn't check.

 

im using 91 octane also changed oil ,spark plugs and air filter...... if i go tune it wil it make a diff? using a vtec controller will help?

 

most likely a cat

 

i replaced tha cat about 6 months ago .....it was a a muffler shop for like 100 bucks ....may b need a better one ? where can i find one ?

 

any suggestions??????????????????????
