i just replaced the upper, lower in take gaskets and the egr gasket and my ltft is still at 16.4 on my gauge, both o2 sensors are new and i dont know what to do now and any advice would be greatly appreciated

unplug the rear o2 let it trip the code and then tell us what the LTFT are doing. it may be getting stuck in the cat efficiancy test and not getting out of it for what ever reason

thats a good idea but im still getting a p0131 code popping up and its a brand new o2 sensor by denso

hmm the code should cancle the the test. check the wiring for the o2

there is also a chance the new o2 is bad

this my second o2 sensor in two months theres no way, but yeah i should check the wiring to the o2 sensor, but what about the maf and map sensor they control the fuel trims also could those be something to look into also

i also about 7 months ago before i purchased my aeroforce gauge, i had a shop do a big 3 upgrade on my car and it was acting funny after that so i had my wife bring it to the shop because i had to go back to iraq( i was on r&r ) anyways so the said they could figure out what was wrong with it cause everytime they put a scanner on it the codes change each time so they told my wife that i could have fried my ecm which being the stubborn person i am said no because it was expensive so would and bad ecm be a good cause or not
