Overheating after changing parts

Ill bet they were the po420/po430 codes. Its a code that boils down to wear on the cat(s). Very commonon on many Toyotas. It is falsely is often thought a weak o2 sensor replacement will help. Acually the opposite. Replacing the càt brings the readings within the overkill emmisions standards.

An awsome fix is a set of cheap o2 extenders. This fools the overstringent "poor" slightly depleted cat's lower oxygen saturation emmisions standards into compliance.

OR spend $$$ for a new cat.

 

Well luckily parts for Tacoma are cheap as hell so I bought a new exhaust syten and cats along with new o2 sensors. And sorry it wasn’t those 2. It was *** P0141***
