EFI service

[othater]

Can someone tell me whats involved with the EFI sevice from the dealer.
I went in for some warranty work and the dealer suggested I should do it the next time I go in for 35K service.
Cost between $90.00-140.00.:thumbdown:
Do they they pour some injector cleaner in the gas tank or do they physically clean out each injector.:iono:
I'm having a little hesitation but not enough to bother, still getting 35+ MPG.:thumbup:
2007 auto Sedan S.

Thanks

skip it. Just something to get your money.


You're better off doing sea foam or running a few tanks of premium chevron.

Agreed. :laughabove: Pop in some Techron and put in a few high-speed runs down the highway! :evil:

[othater]

Thanks for the replies,

I use regular gas with techron in my cars,
Since gas prices are down right now I'll try a tank or two of premium first and if that doesn't work I think I will try the sea foam.

Premium will hurt rather than help....Just get a bottle of cleaner and add it to your tank about every 5000 miles.

Why would Premium hurt?

[b_hickman11]

Because its designed for the low octane and the ECU is formated for using it

[rningonfumes]

Wait, does your car really feel that different? I mean you've only got about 35k on the meter.

As for the ECU>....It should adjust automatically.

I use 1 bottle of Chevron Techron Concentrate Plus every 5K, last fill-up prior to getting my oil changed. 1 bottle treats 12 gals, just right for our tanks.

But the manual stated that Octane used in test was 91?

Unless it's stated on the dash and/or the fuel filler door "Premium Fuel Only" using premium in a vehicle designed for 87 octane will probably just increase deposits and cause longer cranking during start-ups.

Why would you want to put that stuff in? LUCAS products are garbage. You can really clog up the converter and put un-removable deposits on the wide band A/f ( lamda sensor) by doing a drastic "de-carbon"
Be carefull, U can do more harm than good! This stuff may work on an understressed 400CI ford or 396 chevy with NO post catalysis but NOT on a modern auto.

Completely false!

I use Lucas UCL in every tank and I get 7% higher MPG, and no issues with the catalyst, nor valves, nor anything. I also pour Chevron Techron concentrate bottle in tank every 5,000 miles.

I've used Lucas in several other cars in the past 10 years and NEVER any cat problems, nor deposit problems. And in fact the valves on my 1993 Honda Civic are like new clean!

Just got home from work and just checked the forum.
I already filled up with premium.
Maybe tonight I'll take a drive on the freeway, hopefully it wont have a negative effect, but a positive one.
If anything i'll run down the tank and refill with regular and add injector cleaner.

On a car with so little mileage as yours there is no way you are having clogged injector problems but If the plecebo effect of putting higher octane gas in your Yaris is worth the extra bucks then go for it ,just more money in some Arabs pocket.:iono:
As for injector cleaner? another needless additive as its already formulated into the gas you buy,i've ran my last 4 fuel injected vehicles well over 200k and never used injector cleaner and never had problems with an injector,
Your slight hesitation could be a misgapped plug or a plug wire not working properly or just a bad tank of gas.

I had a Honda Prelude Si once that almost didn't make it home because of bad injectors, had less than 10k miles on it at the time. Probably one tank of bad gas was all it took.
I've seen lots of bad injectors over the years. Cylinder misfire counters and injector fault confirmations in the datastream of my scantool make it easy for me to see them. Lucas injector cleaner fixed two out of the three clogged injectors on the last Blazer I worked on. Took care of the misfire counts on all the cylinders except one...had to drag out the MotorVac machine to clean that last stubborn one.

7% higher than what?

[seth_man]

but that will not clean the throttle body or the intake manifold. i dont know what toyota does, but at my shop we use a 3 part EFI system. one is a detergent for the the fuel delivery system (pretty standard, another is "sprayed" into the throttle body with compressed air as a mist in front of the throttle plate (cleans IAC / throttle plate) and then another part that we call the intake snake. basically a expensive cotton ball with detergent on it that we put on a special stick and scrub out the intake manifold / runners if we can get that far down on whatever kind of car. we charge $99.99 for that service. its pretty good if you ask me. i have seen some scary stuff come out of intake manifolds on cars with under 30k on them. even mine.

[b_hickman11]

But the manual stated that Octane used in test was 91?

The manual says "Research 91 octane or higher" meaning before putting in your car do some research to see what the pros/cons will be.

On another note, all gas sold in the US has additives already in it to help cheap the system clean. It doesnt matter if it has a fancy name like Techron or if it is unbranded gas. But its still a good idea from time to time to use an aftermarket product to help clean the system even more because sometimes you might get a bad tank of gas or water in your gas tank. I used to work at a gas station and our computer system that runs the tanks and pumps also had a water level reading. Having water in their tanks is such a common thing that they have to have this system. Also everyone once in a while stations will get a delivery driver that doesn't know what he is doing and might but the wrong gas in the wrong tanks. For example, might out super in the regular. But most stations now have different size tank openings and the tanker has different size nozzles to prevent this from happening.

[rningonfumes]

LOL.... "Research" does not mean for you to research. It's the full term.

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane. http://en.wikipedia.org/wiki/Octane_rating

Let's stop talking "tomaatoes and tomohtoes"... the point is.. don't let the dealor charge you for it, or at least so much for something so simple.

[b_hickman11]

My bad. Thought it meant to check into before hand. Kind weird though seeing how in my area you cant even get 91 octane.....

[SilverGlow]

7% higher than what?

For the way I drive, and the city/hwy mix:

42 MPG + 7% = 42 + 3 = 45 MPG, when I use Lucas UCL in every tank of gas.

[Spades]

your best bet is to just go to a station with certified gas...they dont rate the 87 as far as i know, but, 89 and up are monitered in some companies. less carbon build up the cleaner the fuel you use.

as far as the fuel injection cleaning service, im sure it depends on which dealership you go to. some dealerships and shops i have worked at its a full proccess of addative in the gas tank, liquid cleaner sucked in through a vacuum line near the TB, or a direct injection to the fuel rail, as well as cleaning the MAF and AIT sensors with proper solution and then cleaning the throttlebody.

however, at some shops...it was grab the brakebooster line and shove a hose from a bottle of cleaner to it. some of the "techs" would run the cleaner through so fast it would cause the car to run insanely rich and also blast out the carbon too fast...it would fry or plug the cat.

According to the top tier website (http://www.toptiergas.com/retailers.html):

"Gasoline retailers must meet the high TOP TIER standards with all grades of gasoline to be approved by the automakers as providing TOP TIER Detergent Gasoline."

And thats why its doesnt matter if you buy brand name gas or unbranded gas. It all comes from the same manufacturing plants.

AFA throttle body cleaner - what kind of plastic ( polymer) is our intake made of - I am afraid you put the wrong chemical in there and start melting it. I think there is table on the WWW which show what plastics tolerate what Aromatic HC. We could have Glass-filled Nylon or possibly Dupont talc filled Liquid crystal polymer? I suppose no hDPE ...
