ok my o2 sensors have 62k on them and have seen a blown motor. after my jdm motor was installed I've bin throwing a check engine light, so i pluged up my OBD2 and it says RUNNING TO RICH. the shop that did the install said it's prob the o2 sensors because they have oil and crap on them from the motor that blew. Thoughts please!

by the way the ECU is stock and the mods are aem cai,jdm header, high flow cat, catback exaust.

ok,you running to rich.... Did you touch the gaz pressure?

how can I if the ECU is stock?
