you shouldnt be running colder plugs on a stock car anyway, but it sounds like more than that. like an o2 sensor or something of the like.

i just replaced the narrow band o2 and im catless so the 2nd one is unplugged....i remote start my car alot and it sits and idles could that be it because my aeroforce reads an average mpg of 21
03-30-2009
i also with the aeroforce accidently reset my fuel trim....would that mess anything up? i also accidently ended up stuck doing a case learn awhile back because i selected it lemme know if either of those could be the culprit...

??? You don't have a cat and have the rear 02 unplugged ??? do you have a tune to account for this
03-30-2009
no sir i do not could that be my problem lol

my car reads 15ish on the DIC alot, but i think its just because i start my car up every mrning and idle it for 15 minutes before driving.

yes, My remote start kills my MPG! and having your o2 just unplugged doesent help. get a o2 delete ZZ PerformanceOriginally Posted by gotboost3

Or, a programmed pcm with the o2 delete

So....How long does an o2 Sensor usually last or should I ask how do you know it's bad without scanning?
I have a replacement front o2 that I have thought about changing since the original is about 6 years old but I dont know if it needs it or not as I'm pretty much stock.

the car will tell you when its bad with an SES light.
03-31-2009
so if i delete my rear 02 code then I have no need for the O2 emulator, right?
03-31-2009
yeah i figured it was the remote start and idleing kills MPG's weird thing is i plugged the rear o2 back up and tucked it away and i now have no ses light and i gained a few mpg's
03-31-2009
if by delete you mean on your pcm then yes. you wont need the o2 delete
04-01-2009
yea, i can delete it with my HP Tuners... Thanks!
