Toyota - Tacoma :: 2003 - Gas Mileage Is Little Off - Fuel System Flush?
Jun 26, 2015
I recently bought a 2003 Toyota Tacoma with the 2.4 L engine and 160K miles. It seems to run fine. I took it into my Mechanics Files mechanic to have a couple of things done and he recommended doing a fuel system flush for like $300. My daughter has a 2008 Yaris w/ 100K. She took it to her mechanic recently (on the other coast) and he recommended a fuel system flush (for about $150!!--and she's on the West Coast, I'm in VA). She thinks her gas mileage is a little off (only getting 38 mpg !! ??), but otherwise the car is running fine. If these vehicles are running well, is there any reason to get this flush done? The idea that it may increase gas mileage if otherwise running well seems doubtful to me.

I just bought a 2003 Tacoma 2.4l engine and it has terrible gas mileage.I haven't checked the numbers yet, drive for but it cost medrive for 2 hours. Where do I start looking? The air filter is clean, the tires have plenty of air.

We religiously wear seat belts on the road. BUT, on my 4WD Tacoma, driving around a farm they are not needed. Can you simply unplug the underseat sensor to defeat the annoying chime and yet not disable the airbag system?

I have a 2000 v6 Tacoma.Three days ago I could only get it up to 60mph. Then it started running fine.I drove it about 100 miles an no problem I drove it a litte the next day with no problem.The third day I could only go about 40 mph.I changed the fuel filter and it ran fine. I went out to start it and it would not start. It has spark. I also unhooked the fuel line and it shot gas every where. Hook the gas line back up and nothing. It will turn over and not start.

I have a 2003 Toyota Tacoma pickup. I bought it used in the spring of 2009. I drove it for a few months without any problems and one day this problem developed. It won't start on the first attempt. Or it will start and then immediately die. It will take two or three tries to get it running.
I took it in to my mechanic and he couldn't find anything wrong. I got a tune-up anyway and it drove like a champ. Until the next day when the problem came back. This persisted for a few weeks more and then went away.
This last summer it started happening again and continued up through October and went away again. I think the problem seems to happen when it's hot in the summer.

I am the 2nd owner of a 2003 Toyota Tacoma, 2wd, 140k miles. I've only recently noticed that when I stop on an upward bound hill, and remove my foot from the brake, I will roll backwards while still in DRIVE when at STOP signs, etc. I know that Toyota came up with some 2 peddle fix in later years, but is this to be expected in the 2003? Yea, I know...Tom & Ray would say "keep your foot on the brake stupid", and then move on to the next call...but neither of us is that TOM or RAY now, are we?

When I am coasting in reverse or forward at low speed e.g. 5 mph, I am hearing a whine that seems to be coming from the rear axle.
Usually it happens just after I have shifted OUT of gear (it's a manual transmission).
I uploaded the sound as a WAV file to here: Note! I recommend that you disable flash before going to this [URL]......
When I speed up the whine just rises in pitch and it's making my ears ring. What that sound might be? Maybe I just need some "axle grease" or something?

My 03 Tacoma TRD is showing her years! The truck has about 215k and has some serious vibrations and noises going on. First off I have a constant shaking type of vibration between 25 and 35 mph, but it is also present in the higher speeds of 55 and above but sometimes it gets drowned out. I work at a ski resort so when Im coming down the mtn using 3rd gear or so to slow down I feel the vibration is the most apparent then. So far I have had 2 shops look at my driveshaft and both concluded there is nothing wrong with the u joints. I had a CV shaft installed because one of the boots was torn so I went ahead and had that replaced.
What the vibration is.....2nd is more of a intervalled whooomping sound almost like a bullfrog-like interval. As I increase speed the intervals get faster but it is a drawn out whooomp whooomp not a fast sound. It actually rattles the change in my ash tray to the bpms of the sound. Also I have a metallic clunking sound happening when I put the truck in gear (manual) or start and stop at slow speeds without using the clutch. I was driving around a parking deck the other day in first gear and it would make the sound whenever i hit the gas AND when I let off the gas. ONE MORE THING, whenever I am starting off under load in any gear, the truck jerks.....it hesitates and lurches but only at low rpms and again in any gear.

I replaced my fuel filter on my 2003 2.4L toyota tacoma 2wd. 65k miles. At the same time I checked the valves. No valve adjustment needed. Then i started hearing 4 to 6 rapid metallic clicks from the engine compartment when I start the engine cold. Clicking lasts 1 to 2 seconds. Sometimes happens when engine warm. This fuel filter is not original equipment.

I have a 2003 toyota tacoma 4x4 with the 3.4l engine. Recently I have noticed that while accelerating I am losing power. I first noticed it would surge while going slowly uphill and since it has started happening all the time. I especially notice a serious dip in power during freeway acceleration at around 3000 rpm. The truck has 100000 miles on it. I have changed the plugs, run injector cleaner (the stuff you buy at the gas station), cleaned the throttle body, changed the air filter, and cleaned the mass airflow sensor. I have played a little with the throttle position sensor and that seems to have some affect on the timing of the surge but it is hard to tell. Of course toyota doesn't service the TPS for that year but rather try to sell you a new throttle body $1100.00!!! Could this be the catalytic converter or maybe a faulty injector? Also, I have not changed the timing belt yet.

How long should I let my engine cool down before changing the spark plugs? I have a 2003 Toyota Tacoma 4cyl 2.4l. My drive home from work is about 10 miles and I would like to change my plugs after work but I am not sure how long I should wait before working on the vehicle.

The clutch on my 2003 Toyota Tacoma has been acting funny for a while. I have to pull the pedal back up with the top of my foot about half the time, otherwise it acts like the clutch isn't all the way disengaged when I push the pedal to the floor. The master and slave cylinders have both been replaced as well as the clutch pedal mechanism itself (thought it might be the spring). I adjusted the push rod a little bit and it seems to have worked slightly but it's definitely still a problem.

I've had my XB 5-speed for nearly a year and 10000 miles. It as been dead on reliable and fun to drive. My gas mileage has varied from 26 to 31 in mixed driving and from 32 to 35 on the highway. I use premium fuel only because I can get it without ethanol. My fuel mileage also increased a couple of mpg due to getting the power robbing ethanol out. True it is probably not enough to offset the extra expense but I like not having the stuff in my car. My only dissatisfactions has been with the transmission gear ratios. They are way to low. This torquy engine could easily do with a ratio that would drop about 500 rpm for more relaxed highway cruising.
As it is, though, my XB will go up any hill or long grade without breathing hard! Another is the instrumentation. I don't mind the center mounted set-up but speedometer and trip meter for mpg ratings are both inaccurate. My speedo reads about 2.5 mph high and the fuel mileage read out has about the same error, also on the high side. I have the stock 16" tires. The clutch has a narrow engagement band and can be difficult to be smooth on. The car is fairly quiet, is comfortable and this years hot, humid summer has shown it has one of the best air conditioners I have ever experienced in a car. I thought it might be an electric unit rather than a belt driven compressor because there is absolutely no perceived drag when the compressor kicks on.

My '03 Tacoma Prerunner V6 has 116K miles and recently lit up its Check Engine light, returning a code for a failed up-stream air/fuel sensor. I recently drove across country, using many different fuel formulations ranging from CA gas to midwest ethanol to whatever they put in the gas here in the NY-NJ area (a mystery ingredient that seems to turn motorists irate and confuse their horn as a turn signal.)Anyway- age, or fuel, what killed the sensor? If fuel, will it happen again by time I get back west?

2002 F-150 4x4 super crew w/5.4..So I've got the P0136 code, horrible fuel mileage (around 7 mpg just driving to work without hitting very many lights) and the check engine light comes on intermittently, and I get that code. I have borrowed my friends scanner ("Determionator Scan System") and I can see the live data from the 02 sensors. Today I drove around for a while and watched the scanner and the H02 data, and the downstream sensor on bank 1 shows at most, .09 volts, and it also says its detecting a lean mixture. The code P0136 is for this sensor in particular, and I have heard that an 02 sensor should be around 1 volt. The downstream sensor on the drivers side showed around .75 volts at max.
I believe that it is working correctly, or close to it, and I do not get a code for that sensor. So my question is, is the downstream sensor on the passenger side (bank 1) causing the P0136 code and the poor fuel mileage? also, could an exhaust leak cause the sensor to throw a code and not be bad at all? I do have some very minor exhaust leaks, on both sides of the truck..I'm leaning towards replacing that one 02 sensor. The wires and plug connection to that sensor look fine, plus I would think that if there was a bad wire/connection it would not register any voltage at all.. I have to add, the truck runs fine overall after I replaced the intake manifolds last week. It does still idle high, around 1,000 rpm, after coasting to a stop, then after a few seconds goes back down to a normal idle of around 650 rpm. but idles normal upon starting or in park.

I have read many different threads regarding the TPS sensor on the pedal and EBPV deletes on the E99 7.3L Powerstrokes. I am trying to troubleshoot some issues with my E99 7.3L. Usually on cool mornings and after not being started for awhile the truck will seem to be stuck in an Idle. This is an intermittent problem that doesn't always happen.
I cleaned the connections to the Tps and the IVS sensor and put them back in. No luck. On another note I am also seeing a reduction in fuel mileage and power like the truck is being restricted. I don't know if these symptoms are related or possibly their own issues. I am troubleshooting and possibly thinking it is the EBPV system that isn't working correctly. Considering doing an EBPV delete with a NON-EBPV Pedestal and Flange.

I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?
I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.
My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.
So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?
BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).
