the only way to now for sure is by reading the PCM and knowing what's programmed in there (160 fan settings).Originally Posted by JT2002GTP
But like said already, the 160* will do NOTHING as far as benefit goes! It's not like it will cool the engine to any significant degree... Will only open sooner allowing coolant to flow, but the engine is still going to heat up way beyond the stat settings.
Also the knock sensors are set to activate at the same temp (160*) and if/when in colder environment as I'm sure you get in OHIO, you run the risk of having the engine run at that temp without the knock sensors activated. Overall, people have done it, sure go ahead if that's what you want. But many will tell you it's to no benefit.
As for the p1133, I got it too after my header install. I believe it has to do with the location of the front O2 sensor bung in the headers. I have a high flow cat as well which i think doesn't help. Some have moved the sensor into the crossover, I have yet to try the non fouler trick, but have ability to tune it (code) out which is what I did, sorry.
Replace the O2 sensor, rockauto is your friend here, $30.
And go from there...
Good Luck!
