Due to the old age of the engine I would guess that would be the problem. You can try and run some seafoam through the engine to see if that helps.
My best is ~34.5mpg round trip. I'm wondering if I can break 40mpg with synthetic oils and the coolant temp sensor mod...ASG14 said:Am I like the ONLY person that has managed to get over 30mpg in a Gen 3 V6 Auto?????
Like driving really slow. I get passed by semis all the time... :lol:Toysrme said:Even the vvt trickeration v6's. If you can get 29mpg+ on the Camry platform. You're doing something uncommon if it's consistantly like that on the highway.
In South Africa the Gen 3 came out with the 3s-fe, would i still be able to do the above?Toysrme said:The main thing is replace the two main oxygen sensors. Generic ones are about $30 a pop. Cheeeeeeeeap.
Replace the spark plugs, dizzy cap & rotor, air filter, PCV valve.
Reset the ECU by pulling the EFI fuse a second & putting it back in.
You can also adjust the base timing & AFM cog. Which you should do anyway... It's free power.
You're not far off. Especially if you drive hard.
You oughta get about 24-25mpg highway max. 20-22mpg city max. You should average 23-24mpg.
The correct tire pressure to run would be 32psi all around, or 38psi all around.
