I've just purchased a 170 T stat, but Im getting conflicting opinions on what it will do to my PCM. I was told by one of my mechanics here that by putting it in it might throw a code for engine temp low for to long, has anyone here had that problem, and if so is there a way to reprogram the PCM to accept the change? He also mentioned it may cause my engine to call for more fuel causing possible cat problems???? Any advice will be usefull:dontknow:
