so when im stopped the idle will drop and it sounds like its going to die but it never does, and when im driving if i give it a lot of gas it bogs and wont really go anywhere but if i slowy give it gas it works just fine and it only does that once in awhile.. it is throwing a code for secondary o2 sensor

 

i got same problem

 

your catalytic converter sounds like it is clogged which is why the engines struggling to stay running too hard to push out the exhuast. that will also effect the second o2 sensor since thats what the second o2 is for is to monitor the cat.

 

well i know my cat is bad i was looking at it and it has a obd1 cat on it with the o2 sensor welded into it, i noticed it when i failed referee inspection because of it. so i hope thats it.
