#682 of 2067 Decreasing Fuel Mileage
Feb 01, 2003 (8:30 am)
Have 2002 Tacoma 4x2 Regular Cab, 2.4 liter, 4 cyl. engine with automatic trans. and ABS. A "topper" (150 lbs) is installed but do not carry anything inside. Purchased new 7/02, now with 4,441 miles on it. Vehicle was properly broken in and is carefully maintained, with tire pressures kept proper etc.
Toyota/EPA mileage estimates were 22/25. (I am well aware that these are estimates and conditions will vary same. I primarily drive in city conditions, no undue idling periods, no fast starts/stops...do let engine idle for one minute (when cold) before driving slowly off. I live in Rock Island, Illinois and of course, our weather varies from hot to cold via seasons etc.
I have not had any "ck engine light" come on nor do I have any hot/dragging breaks (ck via careful touching), vehicle seems to roll freely and otherwise performs very well.
My concern is a "decreasing fuel mileage condition". The following are MPG experienced in CITY conditions.
8/02 = 21.9
9/02 = 22, 22.1, 20.4
10/02= 23.7, 21.7, 19.3
11/02= 19.3, 20.4
12/02= 18.4, 17.7, 19.7, 18.8
1/03 = 18.3, 17.9, 16.9
I would appreciate hearing from other Regular or Xtracab, 2.4 liter, 4 cyl, auto trans. Tacoma owners...as to what experiences they may be having with their MPG (and what part of country/weather obtained in).
Would also like to know if any owners out there may have experienced any fuel mileage problems that were ultimately corrected via dealership etc. Pls. explain.

Whatnow2, I saw your post (#611) regarding difficulty shifting into second gear.
I have a 2000 4Runner 5sp and I'm having the same problem. Does anyone know if the manual transmission on the tacoma is the same as on the 4Runner?
Anyways, I posted a detailed description of the problem with my transmission on the 4Runner section of edmunds. The discussion is "'00 Toyota 4Runner 5 speed problem" (or something like that.)
I'd be interested to know if you you got the problem with your truck fixed. There were a few suggestions from guys on the 4Runner board that you might be interested in.
If you have time, check it out and let me know what you think.

Many drivers report increased fuel consumption during winter months. The prime reason for that is the change in the fuel "blend" from summer to winter. Typically, fuel in the winter contains alcohol, which has a lower energy content than gasoline. Your mileage should improve in the Spring.
Also, your vehicle isn't fully broken in at 4,500 mile. There should be some improvement with additional miles.
Check you tire pressure too. Lower temps = less pressure = lower MPG.
Point of interest: I have a '96 extended-cab V6, 5-spd that consistently gets 22-25 MPG.
#685 of 2067 '99 Heater/AC Fan Noise and Vibration
Feb 13, 2003 (8:28 am)
Last night, I started my Tacoma, put the heater fan on and was greeted with a loud and vibrating noise from the heater/AC blower. The noise stops when the fan is turned off. When I drove the Tacoma earlier that evening with fan on, there was no unusual sounds from fan. I know the fan assembly is visible under the glove box, but how easy is it to disassemble the fan to check it out? Is it possible that something from the glove box fell into the fan assembly and is making that racket? I cannot imagine the fan being bad since the truck is relatively new (40 K). Any help would be appreciated, thanks, jerry

my 2001dc4x4trdv6 gets bad mileage as well, like 12mpg. have tried to fight with Toyota, mediation, EPA, and corporate, I think the only was is to sue, have Mech's docs indicating 12-13 mpg. the portable computer (OBDII) they have reads 12-13. but the answer is still pound sand.
I think the truck does everything good except for the fuel and the complaint treatment.
there is a EFI 20a fuse in your engine compartment that you can reset, pull out for a minute. but it is not a permanent fix. The computer adjusts to your driving style (an option I did not know or want). I wish some one can find that line in the code and delete the damn thing. MPG will go back down again in days.
Oh, try to keep alll your service docs too if you can, always ask them to check for MPG. that's if you bring your truck in service, i have no faith in most factory mechs.

I still have the (intermittant) problem 1st to 2nd "notchy" shift. It goes away after about 30 miles at highway speed, but in town, it occurs about 75% of the time. The frustrating part is the random nature of it. When I casually asked the dealer service manger, I got a blank look. I still have about 1.5 years on the warranty, so I might yet get mad and take it in. I haven't been able to see any you mentioned - can you be more specific on a particular post?

Thanks to those who responded rel. their experience. I diligently keep tires at 34 PSI and know that for every increase/decrease in 10F temp., there is change of 1 lb tire pressure etc. Few days ago, filled gas tank (with lowest grade fuel/regular, drove 63 miles on highway with cruise control on at 55 MPH and then refueled. Got only 20.5 MPG on this highway situation. (At this latter refuel...only 3 gals or so, I noted station had their "mid-range" fuel at 1 cent less than the lowest grade of regular...so I used the mid-range. Drove return route of about 75 miles, same highway speed (cruise control) 55 MPH and then filled tank once home (again I used the mid-range fuel)with about another 3 gallons. On this return trip, I got 31.2 MPG. This was all in same day, basically same temperature, same driver, nothing else done to vehicle. I am going to ck fuel mileage (all city driving) over next couple weeks to see if there is any continued improvement with the small addition of mid-range fuel....recognizing that I currently have less than 6 gallons of same in the tank...We shall see.
For the individual who was looking for the "Rattles in Dash Area" TSB....it is Service Bulletin NV00602, Bulletin Sequence #633 dated 5/2002. It's about 5 pages long and provides (Noise Abatement) guidance to service folks on a variety of things/locations that can be causing dash noise.

Anybody know of drive shaft problems on 97Tacoma 4x4 or similar trucks? I had mine replaced (under warranty) at 70K miles, because it rattled. It wasn't the U-joints. I just noticed the rattle is coming back at 96K miles. It rattles at hiway speeds; 35mph or so and above. I don't feel any vibration. I would put some grease in the first one and it would stop for a while, but then return. After more miles, the grease no longer did the trick. I've still got a few more miles on the warranty, but I'm worried about the time after that. Kirk

I have a 99 4x4 xtracab auto 3.4 V6 and routinely get from 20 to 22 mpg at 60 to 70 mph.
