Could anybody provide any additional info for me to verify if I have the correct (NTK??)sensors? I’m currently peaking at 57mpg. Have done the usual: cleaned the EGR plate, RE92 [email protected], IMA recal, cleaned and retorqued ground terminals, correct spark plugs, K&N air filter, Mobil1 oil change. I’m guessing I’m about 95% done and I’ve got to find the other 2-5% that’s “hanging me up! It’s getting a “tad” frustrating.
