When it idles rough it could be several things but, an easier thing you can do 1st is cleat the throttle body of any carbon(black stuff) with throttle body cleaner or something like carb cleaner. Ive used brake cleaner sometimes. But yea, look up your cars info about your motor and just clean all the black carbon off of anything at the throttle body and you may even need to take some of it apart to get down in there with a rag, little cleaning brush and the cleaner. Clean the thing you can move by hand called a "butterfly".

check oil and coolant levels . run fault codes to find failed units.

check oil ,and coolant levels . Run fault codes to detect which sensors put the light on .

I would change the belt first. Power steering is required for all turning but does get a little more usage during hard turns. You will want to check the fluid levels of the power steering pump as well.

Get a manual of the system componentsNo other way to know what your working on,if you have no experience just looking at the cars partsAs far as testing goes, no one can teach you that You may have vacuum to work on, or electricalto diagnose

You have multiple problems in your steering and suspension.Recommend have checked (fixed) ASAP! After repair will need front end alignment as well.Check shocks, tie rods,ball joints,steering gear adjustment, just to name a few.Brake caliper can be sticking too.

Hi there:When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.The Four Most Common Check Engine Light Scenarios and What to Do:* The Check Engine Light turns on and off or flickers.If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.* The Check Engine Light comes on and stays on.If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.* The Check Engine Light illuminates, stays on, and there are performance problems.This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.* The Check Engine Light light comes on and blinks in a steady pattern while driving.Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.
