    (continued) Has had an LPG conversion and I see 2 labelled "heater hoses" going to the valve for the LPG for some reason. Not much need for heater here and I just can't see anything looks like an EGR valve, or many emission controls at all for that matter.

SOURCE: Toyota Corolla DX 97 Engine Light EGR valve PLEASE HELP

You can try cleaning the EGR valve and passages with Seafoam. A bottle costs just a few dollars at any auto parts store or discount store. With the engine running, squirt/spray it in through the brake booster hose, or through the PCV hose. This will cause smoke to come out the exhaust. This is normal and will disappear after a few minutes. If Seafoam does not do the trick, then you can still disassemble the EGR valve from the throttle body and clean it with throttle body cleaner.

Go to and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.
NOTE:.. EGR RESTRICTION POSSIBLE between exhaust manifold and EGR valve... check it out before replacing valve.... replacing the valve may not be the solution... having it properly diagnosed is!

SOURCE: EGR problem on 2001 Camry??

DID YOU CLEAN the EGR air passage tube?

Installed NEW gasket?


Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE

Also remove carbon built up behind the EGR valve and the EGR passage tube.


Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.


EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.

Take it for a test drive.

Please rate my answer if it's useful to you.

SOURCE: check engine light on-code says egr valve is bad

How to clean, the first step, check this procedure:

  1. Park your Toyota in a safe place with enough room for you to work around the front of the vehicle.
  2. Open the hood and make sure the engine or engine components are cool enough to the touch to avoid skin burns or other injuries.
  3. Locate the EGR valve on the engine side, usually on the driver's side. Most valves resemble a metallic mushroom and are about 2 to 3 inches in diameter. Unplug the vacuum hose by hand from the top of the valve.
  4. Remove the pipe connecting to the bottom of the valve using a wrench or adjustable wrench. Remove the two valve mounting bolts using a wrench or ratchet and socket.
  5. Lift the valve away from the engine compartment and discard the EGR valve gasket. If necessary, use a plastic scraper to remove any gasket material remaining on the mating surfaces of the valve and engine.
  6. Clean the bottom of the valve and inlet orifice of carbon deposits using a wire brush and scratch awl or similar tool. Be careful not to score or damage the valve-mounting surface to avoid exhaust gas leaks. Tap the valve body to remove loose carbon deposits. If the EGR valve on your Toyota model can be disassembled, make sure to align the parts perfectly when reassembling. Clean the passage of the exhaust manifold pipe connecting to the valve as well.
  7. Set the cleaned valve in place on the engine using a new valve gasket and install the two mounting bolts by hand. Start the exhaust pipe nut into the valve by hand to avoid thread damage. Tighten the mounting bolts and pipe nut. Connect the vacuum hose to the top of the valve.

Hope this help (remember comment and rated this post).

How do you add power steering pump to 95 toyota tercel

Do you need to replace an existing pump or is your car currently manual steering? If it is manual steering there will be more than just adding a pump. The actual steering rack is most likely different from a power steering unit so there would be multiple components required to convert. If your pump is faulty, you just need to disconnect the lines, remove the belt then remove the pump and install the new one. While you are doing that I would flush the old fluid out of the rack to increase life span of steering rack.

My engine stalls and has a rough idle

In 1991 Tercel DLC is probably under the hood. Try to locate little gray (or black) box that has diagnostic written in the cover. Might be located near battery in 91 tercel.

Battery drains power even when car is off, bought

Someone will need to check all of the circuits to find the power drain.
Could be a stuck relay, short to ground, or faulty switch among other things.

Call a local Wrecking yard and ask them what the interchange is. I know there are some ratio differences between the years. And you have to match the front and rear tooth for tooth.
