ok so after my blowen head gasket repair which included
recon jnjectors from flamethrower
plugs
wires
some temp sensors
the truck seems to run better than before
but I think I lost my mileage

i did mess with the tps because I had a prevous issue and I replaced the tps and set it on truck so I bench set it but then i messed with it again because I thought it was a problem turned out to be bad ground

last check on tps the main setting was in
but I did not check all the spaecs

looking for any ideas
oh cel is not on and I have not run codes (will there be without cel on )

 

Check all the specs for your TPS. If misaligned then it might cause your MPG drop.

The Flamethrowers don't guarantee better mileage. You might have had clogged injectors or poor spark leading to poor combustion and by replacing it all, improved performance and now it's drawing as much fuel as it should have been in the first place.

Why do I know this? I was running on 5 cylinders when I got the truck I have now. Once fixed, my MPG's dropped from 15.5 to 14.0. Course, I've got it back up to 18 now but that's a different story.

 

there is a chance it was on 5 before
i will have to wait till week end to check rest of tps

 

O2 sensor is damaged, O2 sensors don't like antifreeze.

 

Yep, fouled o2 sensors = poor mpg's.

Set that tps correctly as well.
