pte 680 injectors acting funny, also fuel tims dont work

[dsmoverboosted]

Well I got 2 problems with my injector install. First I dont think my 02 sensor is working right but im not sure. I have always gotten a reading from it and my gas milage is good too but My med trim and high trim never change no matter what i do on the safc. My low trim works but thats it. Although i can log my o2 trim while driving at 2000-3000 rpm and it will say bounce around between 30-60% i know i am rich there so it seems to be working but the long term trims dont change at all. They just stay at 82 and 81.2%. Is this normal?

Also I had to set my safc at +3% to get my low trim close to 100% with the new pte 680 (well used). WTF? I thought 680's should be at like 36% and not +3%. Even if say i got ripped and there only 550's there is still no reason to add fuel to get good looking trims. This is only at idle though. if i start driving and i log my o2 trim i notice that it says i am rich at like 2000-3000 just cruising around (since my med and high trim dont change i log the o2 trim while driving) and this is at like - 16%.

I dont get this.

anyone?

i had someone tell me its normal to add fuel with bigger injectors at idle. Is this true? It just seems so wrong.

is there anyone who will help me??? I am ready to pull these injectors out since i need to drive this car and i dont know weather this is ok or not.

If you have installed bigger injectors did you haveto add fuel at idle or is this wrong?

I put in Evo VIII 560's, and it definitely richened up my trims.

If your trims are in the 80's you need to take some more fuel away.
What do your spark plugs look like? Are they all uniform?You may want to have the injectors checked to see if they're all working correctly. Check the signals to each injector, too.
