So i had my ls/vtec swap done about a month ago. Right before i had the swap done my maint req. light came on, so i took it to autozone and they ran a diagnostic telling me it was my Secondary O2. It ran fine and everything until i had the swap done, it chugs now and keeps dropping rpms like its going to stall out. After the swap i took it to autozone again because now my check engine light started coming on only after my car was out of loop mode. It does this everytime i shut my car off and turn it back on now. I took it to autozone again, and they can't get a reading. I also tried jumping it and the check engine light doesn't even come on when its jumped. Has anyone heard of or had this happen to them?

 

its your idle valve control...
you will never get a signal from this...
