OK... Me and my friend been trying to tune my car. My datalogger cable comes next week. But I have a weird reading on my AFC ..

In the Sens. Check Menu.

In-1: FINE
In-2: 0.000 V (02 Voltage)
Thrt: 0.750 V *is this a normal volage?
Knk: 00000

Now... Thats the value's when the car is off.
But the Knk V likes to hit numbers 200 something... to 49.... Which I think are alittle high for not being under boost. But.. The 02 Voltage likes to hit 0.000 when I'm driving. When I'm driving the car studders/lurches around. Any idea what this could be. I have tried leaning it out etc. Now, the voltage at driving should be higher then .0?? right? cause it will jump to .000 to .023 .046 .097 then just to the .??? numbers and then the car drives fine! .... There is no cat could the 2nd 02 be messes the ecu up? Could you guess and try to help me figure this out. Cause it really is getting to me. I smell fuel and shit too. There is a hole in the sidemount and the BOV dump tube alittle lose. But the Greddy24R and the Inake are on there way too. Do I need new 02's? Do I need to wire the 2 02's togather ... and also the TPS has triggers the CEL a few times along wit a Misfire cyc4. The sparkplug wire on the cyc4 likes to come up alittle since there is no SparkPlug cover, and I have found Oil in Cyc4 and Cyc1 chillin around the plug. Cyc4 does leak alittle around the gasket. Cyc1 because the old cap use to leak and blow oil all over, so 1 may have had a little in there still..

Thanks,

ALSO... I have a sensor or something like that by the BCS it, fell apart, the guts inside where hanging done, it looks like a Relay but Im not sure, going to replace it tomorrow, but its strange why it would fall apart ... Maybe that has something to do wit the problem!
 
Not to sure bout your problems... sorry. 2g's dont have a knock senosr so how are you reading knock? Are you sure your AFC is hooked up right??? Keep all settings at 0 till u get a logger. You may have a bad connection between the 02 wire from the ecu to your AFC (the wire you cut) and or the wire from the AFC to the 02 its self.
