p0300 and p0051 codes...

Hi all,

So I posted this on CT and wanted to know if anyone can help me out over here. I have a 2008 toyota tacoma, v6, automatic, access cab, trd sport, 4wd. I installed the doug thorley long tube headers about 2 months ago. After I put it in, I drove it around for a while and about a couple weeks later, I put the URD o2 sim. The CEL always kept coming on so I pulled it out and put the wires back. I put the empire o2 sim in about a week ago. That didnʻt help either, still had the CEL. So yesterday I installed a scangauge and it gave me a p0300 and a p0051 code. Anyone know or can help me out. I know what the codes mean but I donʻt know where to start.

Thank you in advance.

P0051 code relates to the 02 sensor in the exhaust manifold located on the passenger's side.

Several may have the answer on here. But they may not be logged in at this late hour.May have to wait till daytime to get your answers. I have seen this before on here, but do not remember what thread it was on.
