So for the last month I have been getting this CEL (although today I actually went to see what it was). Before I knew what it was i replaced the gas cap, MAF o-ring (and cleaned it), and thats about it.
I went ahead and searched the forums for what seems to be the most basic fix and I found equal amounts of different solutions. So first off let me explain my set up and what I have done. I have a Che header, downpipe (so no cat obviously), and megan racing exhaust. I replaced all 3 o2 sensors in december (same time as exhaust, except the header which was done last summer). The o2 sensor on the downpipe is one of the spliceable kind from autozone. I spliced it with there splice kit (so all the wires are in a little gray box). Like I said everything has worked fine up until now. When I pull the o2 sensors out however, they all have a layer of white on them (not sure if that is normal)? Also on my downpipe I am using the o2 simulator that comes with ches downpipe + 2 sparkplug antifoulers. The reason for this, is on my last setup I used nothing but 3 sparkplug antifoulers (Thats how many it took to stop the light from coming back on, and it has worked fine since last december).
The second fix was exhaust leaks. I have all of my heat shields on so this is kind of hard to go out and test right now. However I will admit that my only real toyota gasket used was on my header. The 2 donut gaskets and the gasket from the downpipe to exhaust is all Ches and megan racing's. Before I put my heatshields back on (at most 2 months ago) the downpipe to exhaust was leak free (same with header to head I believe). I did however have a very very small leak from the header to downpipe which I used some exhaust paste to fix. Would this somehow cause the code to be thrown?
I will also throw in, I have the innovative mounts so I dont think much of the exhaust has moved much

. I just went outside and took out one of my spark plug antifoulers and then I drilled the little hole on the other one to make it a tad bigger. Now I have the o2 simulator and the sparkplug antifouler with a little bigger hole. If this doesnt help then I will move on to gaskets. If those dont help then I am taking my light bulb out and buying a cel reader to check my car every so often for other codes. (In case this bothers anyone, I have no intention on selling my car. It is all paid off and I have done to much work to sell it and not lose a ton of money)
