did you find the sulotion to the issue please update

 

May be try to check if bough of your fuel pumps work fine. Especially do that if your IDLE issue is any different when you are running on reserve fuel. Easiest way to check is - in the engine compartment driver side, right by the windshield, pull plastic cover, turn 3 "locks" pull fuse box plastic cover. Try to remove fuse number 13 ( 15amp - blue incolor) test vehicle driving abilities. This will make your vehicle run on the one fuel pump. If you will drive the car you should fill some loss of power and vehicle is not as responsive as it normally is, but decent over all. Then reinstall fues 13 and do the same with fues 14 ( same type of fuse - they are one next to each other). This will swap the fuel pumps. vehicle should run decent as well.
If vehicle does not run more or less normal then you should consider replacing fuel pumps.

I do not really believe this is your problem, but I had an issue with one pump on my car and vehicle was acting so weird from dropping rpms and stalling to jerking, erratically gear shifting and behavior warred with amount of fuel in the tank. All was fuel pump which would work from time to time...
