pull off air intake duct and clean with carb spray and open throttle plate and scrub inside as far as you can and get all the crap out of there.

take it all apart and unclog it make shure you remember where it all goes or you are SCREWED

You will need to remove the throttle body and replace the throttle body gasket. The throttle body gasket can be purchased at most auto-parts stores.

Clean the throttle body with a spray throttle body cleaner.

Butterfly in the throttle body needs cleaning.

Use throttle body carbon cleaner, you can find it in any auto part store.

Chances are the throttle cable from the pedal to the throttle body needs replacing.

PO506 is Idle Air Control (IAC) system idle lower than expected. Can be cause by: Vacuum leak Clogged Air filter or clogged Catalytic Converter Faulty PCV valve Dirty throttle body Internal Engine Problem In rare cases a failed PCM

to fix that problem with it cutting out let it warm up a little bit before like 30 40 seconds or so and then barrely pull in on the throttle and then just give it more throttle steadly and after that it should be ok

Spray the throttle body (carb) with cleaner, not carb cleaner. You should use throttle body cleaner because there is a coating on the throttle body that will be removed if you use carb cleaner and that coating that comes from the factory should not be removed.

Determine the cause and fix it. Could be as simple as cleaning the throttle body.

if throttle body is flooding engine how can i fix .4.3engine on 88 Chevy blazer motor was running great on morning wont start. new gas tank plugs wires ,sending unit.and throttle body.motor turns over wants to start ,there is fire to plugs and fuel to throttle body,also new rotor button

If you have a cable operated throttle body it's probably a bad idle control. Depending on your parts supplier they might call the idle control an IAC or ISC or IBP. If you replace the idle control, you should first clean the inside of the throttle body thoroughly using throttle plate cleaner and either a soft brush or a rag, then run the engine for a few minutes. If you have an electronically controlled throttle body, suspect a damaged throttle body or a broken wire near the connector at the throttle body.

I had same problem with my 98. Mine was the throttle body area. What happens is the throttle body gets carboned up and makes the accellerator sticky and causes the hesitation... To fix: 1. remove the large rubber intake from throttle body. 2. start engine. 3. spray throttle body cleaner (large amount) inside butterfly area of throttle body as you rev the engine to keep it running. 4. done.

The tps is built into the throttle body. You need to buy a new assembly. I just had this done to my 08 5.3. Make sure you take it to a shop that can zero the throttle after this is done.

U need to clean the throttle body and also clean the idle air control vavle

This may be due to 2 reasons. One is the fact that the throttle body bore has a groove worn into it due to a worn throttle shaft bearing. This cannot be fixed as you will have to purchase and replace the throttle body. The other could be a frayed or binding accelerator cable.

I had the same problem for almost a year and damaged both engine mounts and trans mount. The fix was simple. The throttle body was gummed up and sticking. Took it apart and cleaned it with carb and throttle body cleaner and no more sticking. Smoothest pedal in a year.

If your truck is overheating!!! Then check the upper radiator and lower radiator hose's , if the lower is cooler the the upper the either the thermostat is not opening or the radiator is clogged

Its not a kickdown cable its a throttle pressure cable. Take it to your local shop. They might do it for free. If not they might do it for an hour of labor

yes take it out and T bag it

I believe Toyota went to a an electronic/electric throttle design in 2002. There is no mechanical connection. A spring on the accelerator pedal returns it to the start position. There are products available at the parts stores for freeing up the throttle body. If you have a car with a mechanical hook up to the throttle body you can free the cable up with products available.

Drag them to the red boxes in the workroom , they will automatically fix the shower
