What have you done to your Tacoma today? 1st Gen Edition

Yeah the winter gas here sucks donkey nuts. I'm sure they're adding more ethanol/additives than ever before given the massive traffic influx.

And for the record I fill up at the same gas station 95% of the time.

For the most part, yes, same route, area and type of driving. The traffic pattern has definitely changed. Too many facking people living in this area.

I don't let it warm up much longer or too much. Always wait for it to drop down a bit from the initial high idle. Then I drive it slowly and mellow until it warms up considerably.

The problem is if I get a stretch of commuting/travel where it's those ideal 45-50 mph back rural roads for several days in a row... I'm still getting the significantly diminished economy.

Without a doubt the aftermarket front bumper is the most significant impact on fuel economy. I remember it from years ago when my buddies and I were into Broncos. I also remember Viking Brett's experience once he put on his front bumper.

 

I'm assuming you've regeared?

 

Well i know i get better than 12 on the highway haha....when it is driving. And I wouldn't be driving it now anyways.

Off the highway...yeah its probably still worse...but thats my lead foot talking mostly.

 

no he hasn't.

 

My money is on the crappy gas.

 

If I spent my time trying to track down a 1-5mpg loss on my truck I'd have to quit my job. I just fill my vehicles, it pretty obvious when something major is wrong even then.

 

If I was only complaining about mpg in winter, yeah you guys could slap me silly.

But it's also noticeably less economy in the spring/summer months too.

I think I'll get out of bed, get the wallet and order a UG. Maybe that'll tell me something about the cat or O2 sensors or something.

 

It just sucks not having the same range as before.

 

Bigger gas tank? I bet you'll learn something after watching your O2 pids and LT and ST trims.

 

Any tire size/type change during this time of mpg change? Or wheel alignment?

 

Still running 31x10.5 r15 All Terrains.

Was gifted KO2s over the summer but the drop in economy was significantly noticeable when I was still running the Goodyear Adventures.

Wheel alignment numbers are still the same.

 

Yeah the fuel trims is something I want to monitor. I just ordered the EM Plus. We'll see how this goes.

 

can go to a parts store and they can read it for codes as well.

 

Cant say ive ever heard of a warped/uneven surface of a torque converter.. But i have had 2 torque converters on the newer Camrys for the Trans shudder fix that have come from the factory machined wrong and wont mate to the trans itself.. your truck just doesn't want to be 4wd just yet.

 

I've always driven like a depressed grandma

I ordered a UG last night (with two mounts, horizontal and vertical, because I have no idea where I'm going to put this thing) so hopefully it will give me better diagnostics to go off of.

Out of curiosity was it a PITA to calibrate for accurate mpg? I read the process years ago but can't remember.

 

I too need to calibrate mine

 

Nah you can do it really fast, redid mine a couple days ago. Takes some division and a good GPS speed to cal.

 

I'd be interested to see if that helps you, just got a pending code of a TPS issue the other day and have been fighting extra shitty MPG as well. Truck is def still due for some love, fuel filter, wires, plugs, and a clean MAF/TB def needs to happen sooner rather than later. 230k on it now.

 

It's been over a month since we've discussed this

I've replaced the TPS twice now. My idle was extremely high and my rpms were noticeable higher when in gear also.

That should make a big difference with your mpg honestly.
