My check engine light is on i keep getting the code po410 and it is ideling really high sometimes

could be that at idle speed there is either not enough pressure to keep fuel getting to engine. the fuel filter or fuel pressure regulator are keeping the fuel from reaching the injectors. The fuel pump is probably ok else you could not start it in the first place. One other part could be the oxygen sensor on the exhaust manifold needs replacing as well. If your idle RPM is too low your engine could be struggling so if you cannot push down on accelerator to keep it going, it should be one or more of the afore mentioned possibilities. it is hard to find a auto store with an ODB 1 engine code reader, but if someone has one this could identify the specific problem. Mechanics usually charge a really high amount to check this for you. Check your fuel lines for leaks and then those items i mentioned above. Good Luck.

first ensure your spark plugs, wires, cap and rotor/coil packs are in good shape. once thats done check for a check engine light, sometimes they come on then go off but a code will be stored regardless. once you have made sure your getting good spark and there are no trouble codes the issue is most likely a dirty throttle body or fault IAC (idle air control) valve or throttle positioning sensor. hope this helps, good luck

This has to do with the secondary air pump system, this system is used at cold start-up and involves three components; air pump, solenoid valve and a relay. Many times the valve becomes stuck or clogged, the relay has also been known to fail.

You may want to check for a broken vacume line it will cause a high acceleration. Also have the code extracted and see what it says let me know or post it it would be helpful in giving you a more precise diagnosis.

Most Lesabre have the 3.8 engine. The engine has a device called an automatic idel speeed motor or AIS for short. It's held on with two torx 20 screws and a 4 wire electrical connector on the side of the Throttle body. BUT BEFORE YOU GO REPLACING THIS DEVICE THAT CAN COST OVER $50. Try this first. Don't drive the car around this way just test it! Remove the big vacume hose from the power brake booster and put your finger over the end of the hose going to the motor. Have an asstant start the car and hold the gas so it'll keep running, trying to go as slowly as they can. Slowly remove your finger from the end of the hose and the motor should pick up speed. you should be able to get a good idle with your helper completly of the gas. if you do the idel motor is'nt working ( right) so your not done checking. Let's say you can't even get a fast idel that stays. The timing chain needs checked and other vacume or engine control codes need checked. Has the check engine light been on? ( with the engine running) . If it has the idel motor will set a code as will a cam senser and all the other sensers on the car. Follow code charts if a code is found. Most auto parts stores will check your car for free for codes but their recomendations very with the experience for the operator of the tool, and if they were good enough to make the mechanics money why are they in a parts store? If you can acheive a good idel playing around with the vacume hose then put it back on and go to the next step. Remove the Idel motor and clean it and the hole it came out of with oven cleaner. Just like cleaning an oven don't get it on you or the wiring part of the motor. With an OHM meter the pins will show two different pins hooked together ( two Pair) If you get only one it's bad. Every pin is connected to just one other pin. If not it's bad. You can get new cheap ones that are bad. I use cheap ones and cross my fingers. If they work the first time their good for a long time. Then you have to learn the idel. Try to learn the idel with the old one cleaned first. Start theengine and hold the idel with the gas pedel. after holding the speed at 2000 Rpm for two minutes ( a good engine will do this easy) let off slowly it should idel down slowly then (catch) and speed back up on it's own. If it does your fixed and go on your merry way.

change CO2 sensor

check for a loose battery or engine ground also check for loose engine jacks

Check for a vacuum leak around the intake manifold area.It could also be something to do with any of the sensors mounted on the intake manifold,although they should set a trouble code.Manifold air pressure sensor,throttle position sensor,mass air flow sensor,idle air control sensor,etc.Take some brake cleaner or WD 40 and while engine is idling,spray around the intake manifold.If the engine speed goes up or down in relation to your spraying,that's the area of the vacuum leak.Good luck.

The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. We recommend buying your own scanner and doing it yourself. With a pocket scanner you can check for fault codes to find out why the light came on in the first place. You can clear your cars trouble codes after you replace the malfunctioning sensors.
