Ok its my friend car the check engine light alway come on after the car is warm it's a si model.He replaced about almost every sensor except the o2 what could be the problem? and car runs great so idk and help thanks

 

Whats the code the ecu is throwing?

 

im not sure how can you pull the code?

 

Look at the ECU, it has a little red LED that will be flashing, the flashes correlate to a code.
