Ok, so when I got my GT brand new, my mileage was averaging in the low 30's per gallon. Granted, 75% of my driving is done on the highway. The only true power adders I have installed are my AEM CAI
and my TRD
exhaust. Lately I have noticed that my mileage has been significantly lower. I'm talking in the mid-low 20's!! So then I went into troubleshooting mode. I cleaned my Air Filter
, cleaned the MAF, changed the spark plugs, cleaned the throttle body, and changed the oil. I have kept up with all the maintenance. Yet, my mileage doesn't improve. I do have roughly 62,xxx miles on my 2002 car.
I just got back from Atlanta cruising down I-95. I got 300 miles with 3/4 tank of gas. That's high twenties, maybe even 30 mpg. It should be better.
So now I'm thinking it's the CAI
. My hypothesis is that since the AEM
unit is a quarter inch larger in diameter than the stock air Intake
, more air is getting into the engine. With more air means the MAF is telling my car to add more fuel to go with the air. I've read up on the Blue Bomber hybrid Intake
setup, and I'm wondering if that improves gas mileage. Because technically, the only amount of air that is getting into the engine is the amount of air the throttle body is letting in, which is sized to math the 2.5" Intake
pipe of the stock unit. So I'm thinking if I hybridize my Intake
so that the MAF is mouted on a piece of 2.5" pipe after the 2.75" AEM
pipe, the MAF will start to act correctly by adding the right amount of fuel for the right amount of air.
Does this make sense? Has anyone solved this problem?
