Good Fuel pump/injector cleaners?

[rockhard]

I have problems accelerating after my engine reaches a certain temperature or speed so I belive there is some carbon build up somewhere in the fuel system
so its about time i need to give my 85 camry fuel system a good clean.. but do I need to have some special type of special machine to clean my fuel system(fuel injector/pump)? or is there something i can use to do it on my own.

The pump normally does not need cleaning. How is the fuel pump. pump filter in the fuel tank and fuel line filter? Toyota has a TSB on cleaning injectors. Basically they force Techroline through the injector rail and then injectors. Try adding something with this additive to the fuel tank when it is low on fuel.

Chevron is quite highly used as fuel injector cleaners.

Or you can do seafoam, which usually produces great results.

you can use seafoam in your gastank

well i tried a fuel pump cleaner that you add into your gas tank then I was about to take it for a good run on the freeway but it didnt seem to work after I was driving i still noticed the same things...
my car wouldnt accelerate very well at all going up hills and somtimes on flat road it wouldnt accelerate very well at all either..
after I did about 20-25 mins of driving my car i Tried to bring it up to 60 mph in 3rd and slowly the car lost power, started to deccelerate and i pulled it off to the side of the road then it stalled so i think i have a bad fuel pump and filter
what do you think?

hey recently I have found out about throttle body cleaners and fuel injector cleaners I used the Fuel injector cleaner in my gas tank, replaced my fuel filter and now the car will at least run but I want to clean my throttle body because the car only accelerates when there is high RPM's but at least it accelerates....
the guy at walmart recomended I use this GUNK CARB MEDIC - carburetor cleaner... I am pretty sure my camry doesnt have a carburetor but he said to spray it into the air intake on the throttle plate...
should this stuff still do the job?

Most carb cleaners can be used to clean the throttle body. Just make sure it says O2 sensor safe on the can.

Would use Seafoam in gas tank.

Sounds like your performance problem may be electrical related - usually the fuel pump is either go/no go, it works or it doesnt. Ive heard of them just dying gradually but i have never seen it.

Maybe you just need a tune up, when is the last time you changed the distributor cap, rotor, plugs and wires. Also maybe you need to do a compression check too.

well I was able to borrow a fuel pressure gauge from a friend and i did the test and the fuel pressure was running at 15psi the far from the usual at 33psi so I bought and replaced the fuel pump (OH Man.. its a pain getting that tank off and back on) but now my car runs like normal....
If anyone knows Im wondering were exactly the fuel injectors are located, I think I can see where they are but Im not sure, I would like to remove them and do a thorough cleaning job still.... my engine is a 2Se
any info is apprieciated.....thanks

Wedged between the fuel rail & lower itnake manifold.

[rockhard]

thats what I thought, they branch of that long metal tube mounted below the Efi right
Do I need to remove the Efi to get to it

Rock,

Get a service manual and start rippin'....I've had a 2SE all the way down to the head and it really wasn't that hard.

Good luck!
