Ok I put a big *** Super T70 on my obd0 b16 stock block with GSR cams. Ran it open DP for about a month. Just got my 3 inch exhaust done yesterday and noticed that around 7000rpms to 8300 she falls flat on her face(meaning she leans all the way out where the AEM wideband reads below 17.00)?? Im confused on what would cause that??? Im also running a high flow Catco cat which will be removed earlier next week. I've richened up 7 grand up and no changes so im sure its not the chip

Just realized that the Wideband seems to be acting up as well?? Sometime the car reads 14.8-14.9 and just stays there. I rev it and it doesnt even change. is there a life span on the AEM widebands or some sort of cleaning procedure that needs to be done every few months???

Any input??

retune with the exhaust

da_dude

I heard that the AEM wideband goes out quicker then the other wideband,

I think thats what the problem may be...other problem is that it isnt mine. Is there some sort of warrantee that comes with it??

DaveF

did it get wet(the sensor/connector?)

D-meet07

hard to say. I have it right in the middle of the bend that comes from the turbo to the oilpan. Not really sure if it got wet??? But I dont think so.

It seems to act up until it gets warm then it acts halfway decent. I may just spray the plug out with contact cleaner and dab it with a little bit of electrical grease.

DaveF

is the sensor perpendicular to the pipe? or it is aimed upwards or downwards? the position of the sensor may have something to do with it, the condensation will wreck shhh fast.

D-meet07

yeah its up and down the pipe???

DaveF

is your similar to this ?

D-meet07

yeah:

would a manifold leak cause this with a cat that would be somewhat restricting??? I dont understand. Open DP and everything was good. New exhaust and lean conditions after 7000rpms???? im clueless.

DaveF

your 02 placement looks to be fine. the leak in the manifold will definitly throw off your a/f, im suprised the car isnt breaking up or something to that nature. the cat would cause a bit of restriction as well, but i would think it would get more rich with the cat on, as opppsed to being lean.. with the open dp. try getting rid of the leak wherever it is on the manifold, and see how it goes.

D-meet07

that will work. The leak is not affecting how much boost im running thats why I didnt think anything of it. But I will definetly get it fixed. What does the leak do??? cause the turbo to possibly spin to fast which in result is more air,which leads to not enough fuel maybe???
