YOu may want to have your EVAP system checked. IF the ecu is getting the vapor from the charcol canister it could be burning more fuel in its place. Also you may want to check to see if your charcol canister is full of fuel. Your evap system could be dumping fuel there. Or you could have a leak but, i'm sure you checked for that.

 

i am sure there is no leak. can u tell me pls where is the charcol canister so i can check. and thank u for ur help

 

Its in the back. You can follow the hose from the gas filler tube. Its located in the center of the vehicle right about the rear axle. Its plastic and has a couple of valves and a bunch of hoses on it. If you remove it make sure you label the hoses so you know where they go back to.

 

lavalleemike.. where r u located maybe i can take the car to u and u can help me find this problem.

 

I'm from texas.

 

i checked the canister and is good , no gas inside,can it be the fuel ing. system . my mechanic has that par of an engien he replaced. lavalleemike pls help me out . anyother thnig i should check. me mechanic only wants me to keep spending money.

 

i would check your egr system next. there is no gas smell or somke when you drive... It has to burning rich if its not leaking. have the emissions checked on it and see if its burning to much fuel.

 

you can save alot more gas by lowering your RPM but i dont no about the damage it might or might not cost

 

THAI your offically a moron

 

ok, so lavaleemike seems to be the only one on this forum that seems to be helping out.

as for the gas mileage you seem to be getting, wow, i dont really know what to suggest...
ok, so the computer only said maintenence, nothng more? no check engine lights or anything?
if you're stuck, i'd recheck the fuel pump, filter, and injectors... but you've probably done that, so i dont know
