hi guys trying to track down my cars cold start problem i pulled some codes 31/32/33 these i all know about (i removed all the emmisions crap)

the weird one is 17 -Feedback System No change for 25 sec in feedback mode.

I have no idea,,,,anybody help? what does it mean

 

The ecu is not reciving the signal it expects from the O2 sensor. Car is either way to rich/lean when it wants to go in to the feedback mode or the sensor is bad. Doubt it has anything to do with a cold start problem.

 

ahhaa,,, so its either dodgy O2 sensor,,, or maybe because i have removed emmissions crap??
