SOURCE: no acceleration

I had the same problem with one exception. It would rev higher than 3500 but the higher it revved the more it bogged. I had the catalytic converter replaced. I thought I bought a new car. Acceleration is just like new. It was easy enough to test. My mechanic cut a hole in the exhaust pipe in front of the catalytic converter. It sounded like a truck but the acceleration difference was immediate. Easy diagnosis.

The car is hard to shift because the more you press on the accelerator the more the computer for the transmission won't let it shift. Which in turn causes the car to bog more sending more unburned fuel into the catalytic converter. Which in turn causes more carbon build up and more back pressure. Vicious cycle. It will only get worse.

My thermostat caused the entire problem. Thermostat was stuck open, engine never got to operating temp most days. Car burned rich. Bad gas mileage. A lot of unspent fuel being dumped into the converter. Probably have some underlying cause that needs to be addressed. Bad plugs, wires, coil, fuel filter.

SOURCE: throttle body reinstalled, firebird idles at 3k rpms?

You have a vacuum leak for sure. Look and listen carefully for anything left off, maybe an egr valve or pcv hose, brake booster line?

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.

check or clean out throttle body at throttle plate it may have carbon build up on it. also make sure air filter is clean and check or replace the intake air tempurature sensor.(iat) sensor. the sensor is under 20.00, the sensor is after air filter in the big hose to throttle body.

How can I fix high idle?


In theory once the desired idle speed is programmed into the management system, in the absence of such faults as air leaks, sticking idle air control valve and suchlike it should be impossible for the idle speed to be much different from the programmed value because the ECU should continue closing down the amount of air bypassing the throttle butterfly until the idle is around the correct value.

I think you need to go back to basics and double-check the work to ensure everything is as it should be. In the absence of mechanical faults and ignoring the possibility of electronic problems a high idle must be caused by too much air entering the engine, either because the idle air control valve is not closing properly or because the throttle butterfly is not closing fully.

It is worth noting air can enter the intake through leaky diaphragms, split vacuum hoses or faulty pcv systems. It is also worth checking the egr valve if fitted.

How do I do a throttle body replacement relearn on a 04 isuzu ascender


The relearn is done by unhooking the battery for 30-60 minutes. With all HVAC OFF, hook the battery back up and drive your Ascender around for about 40 min or so, at this time, it will relearn. To test it, stop the vehicle put it in park and turn your AC on, if your car doesn't show signs of boggin down or trying to die on you, your relearn was done correctly. This is all assuming that your throttle body is CLEAN!!! If it's not clean, your idle will be bad and engine will try and die on you at idle when your AC or Defroster are on. Relearn should of already been done---> you always disconnect the battery when cleaning the throttle body, as to not to damage the stepper motor that moves the butterfly. To properly clean the throttle body and for best results, always remove the entire throttle body and clean BOTH sides with a sensor safe spray like Seafoam and a rag or nylon brush, you can reuse the hard plastic gasket. Hope this helps!

How do I adjust the throttle body


The throttle bodies on most newer cars are not adjustable for its idle speed. If the Check Engine Light is on, go to the nearest auto parts store and get them to pull the error codes from your car's computer. Post the codes back here and we can give you a better answer to your question

Hight idle


Bad idle solenoid. Located on throttle body. It's black. Plugs in to wiring cable. You need a torx bit to remove. It's a cheap and easy fix. Also, get some throttle body cleaner and a tooth brush. Saturate the inside of the throttle body with cleaner and scrub out the black soot. Do this with throttle body in wide open position. Be sure to clean the edges of the butterfly good. They soot up and stick preventing throttle body from closing all the way.

Warm or cold, my 4.7L V-8 jumps up to 1,500 rpms every time I start it. Then it immediately settles down to 600 rpms. I have replaced the TPS sensor, but the problem remains.


throttle has a lot of carbon build up need cleaning. if check engine light flashing code scan for code.but more likely could have clogged air filter.idle air control passage clogged dirty.check make sure throttle body linkage not binding sticking.

The oil pressure has begun to falter sometimes while idling, even causing the car to stop briefly.


The idle RPMs are probably too low because of a dirty throttle body, clean the front and rear sides of the throttle body thoroughly. Also, disconnect the battery while doing the cleaning, this will reset the computer and allow it to relearn to the newly cleaned throttle body.

Hi i have a code reading P0506 for a 06 GMC Envoy XL any recomondations


{: ) DTC P0506 Idle Speed Low
The usual cause is an excessive carbon build-up on the throttle body. If this is the case, I suggest you have your throttle body cleaned and perform an idle relearn procedure using a GM scan tool. The idle relearn or reset procedure is very important, otherwise this code may still remain even after a throttle body clean.
In a similar fashion, if the ECM/PCM (engine control module) of a high mileage vehicle is replaced and/or reprogrammed without performing the Throttle/Idle Learn procedure, the ECM/PCM may no longer compensate for existing carbon build up in the throttle body, causing it to return with a similar concern as well as DTCs P0121, P0506, and/or P0507.
There are other conditions that can also affect or reduce idle speed by increasing engine load like incorrect torque converter clutch (TCC) operation, accessories that require additional torque to operate, restricted exhaust, and mechanical conditions that limit engine speed.

Has low idle and wants to die when a/c is on when idling. Then when i accelerate, it sounds like it is shifting at high RPMs.


The low idle and wanting to stall is caused by a dirty throttle body, it needs to be cleaned thoroughly front and back sides using throttle body cleaning spray. Also while doing the cleaning, disconnect the battery to reset the computer so it will relearn to the newly cleaned throttle body.
