My car just pulled a code 67, now ive been running header and straight pipe, just put a stock muffler on tonight, would resetting the ecu help this problem out? Please help asap.

Thanks in advance, matt

its a d16y7 with stock everything besides header.

 

bump

 

ne1 have an idea?

 

bump, code still here, im running a two piece header also, if that helps any..my car doesn't have a cat converter...would that cause the cel? It didn't come on till about 10 min or so of driving.

 

I reset the ecu and code went away.

 

Well the code will come back but sense you took the cat off you have O2 sensor after the cat you will get that code until you put the cat back on...
