GETTING 10.4 MPG 2006 trd v6 manual

Ok so what code(s) do you have?

 

Start with the O2 sensor code. Can't ignore a known code, especially oxygen sensor related. Those sensors are super important for fuel calculation. If there's leaks downstream of the converter then it's possible there's more exhaust leaks near the A/F sensors. Fuel trims would shed light on that

Don't waste your time with spark plugs and fuel injector cleaner

 

what's the weight of your tires?

i just went to a C-rated Ko2 from a p-rated AT34S and took a hit lol

 

i can’t remember if it was a p0420 i’ll this week and get back to you

 

@b_r_o how do you check fuel trim do i gotta bring it to a shop? can i find the code and maybe just replace the sensor?

 

stock tires and rims 16 inch rims not sure what size tires

 

230,000 km. Are you still on original clutch?

 

Scan tool

 

@Desert Dog no idea i got the truck 2 years ago, clutch feels good though no slipping or grinding just a little bit of a noisy throw out bearing

 

like an obd scanner??

 

Yes

 

Some have capability to read fuel trims.

For some long reading on fuel trim.

230k+ kilometers, your OEM fuel filter is quite saturated with contaminants.

Check over the vacuum lines, and their ends for splits and cracks.

Obviously the exhaust code.

Replace either the whole fuel pump assembly, or install the URD fuel pump upgrade with replaceable fuel filter.

 

A fuel injection cleaning service could also help. Back in the days before I to FB, the Aussie Toyota groups had documented that their aged injectors were not flowing as specified. Sometimes cleaning worked. Other times replacement was necessary.

 

Dragging brakes might cause issues

 

Definitely get some photos of the brakes as well. ^^^

 

did you try the lead foot delete?

 

man this is me driving conservatively, lead foot would be like 5mpg

 

okay this weekend i’m gonna check everything out and get pictures and what not
