Question about Hyundai Elantra
After replacing all required sensors on 2001 hyundai elantra, map, iac, tps, and all possible vacume leaks, still will not idle properly.
Have you used a OBD-II scanner to find your issue? The car will help you find out what is needed to fix it. Remember to clear the settings after fixing something. This will help pinpoint your issue. If the same issue arises then the issue is another part. Read those codes supplied with the unit. It will help eliminate possible multiple problems. I have included what the codes mean in the following link How to Read an OBD II Engine Code Best of luck

The problem is in your steering wheel

I think you have ruled out the engine with all the parts you have replace. The transmission torque convertor is in lock up mode all the time. The engine is having to hard of a time to stay at the normal idle. The over drive clutches and soleniod are most likely damaged in the transmission.
I think you should take the vehicle to a trasnmission shop , The can check the torque convetror soleniods and pressure control soleniod.
The oil light coming on bothers me. I know you have the rebuilt engine in the vehicle but I think the oil pump in the engine is starting to go out or could be weak. The lower bearings connected to the crank shaft might be starting to leak. Have the oil pressure checked .

You can clean the EGR. No promise it will work. I have an idle problem on my `97 Grand Am Se. Shop told me I could clean it and it might solve my problem.
Just remove the EGR with the 2 bolts from the top of the manifold behind the throttle body if you have a 3.4 v6 like I do. Then leave it upside down with throttle body cleaner in it. Fill the EGR level with cleaner and let it soak for at least 30 min or more. Then reinstall.
This will remove any carbon on the inside which plugs the needle from pushing out at highway speeds. Hope this helps. If the problem returns in a week or so then replace with new EGR. New EGR is about $100-200! Cleaning seems to have helped my car did that about 3 weeks ago.
If you have a service engine light on turn the key to the run position on the ignition, pull the fuse to the ECM (batt) and disconnect the wire harness to the EGR. Reinstall it after a 1 min, That will clear all the codes in the ECM and reset everything.
Once you place the ECM fuse back in, start the car. It may stall but let it, DO NOT TOUCH ANY THING. The ECM need to relearn the EGR and engine from all it's sensors like the first time it was started. Just start it up again and it should be like the day it came off the assembly line and will relearn everything.
Good luck and just drive it like you always. If you decide to change the EGR valve, you still need to clear the ECM as mentioned above for the ECM to relearn the new EGR valve. Hope this helps and keep me posted.
