Fuel to lean

I recently put one of those injector cleaners in my 2001 sonata. When I went to get the oil changed they also put one of those injector cleaners in the same tank I put the first one in. After that the eng light came on (it read fuel to lean) and my car has been boggling or wanting to die when at idle. What should I do to make it run better and not want to shut off when at idle? I'm already on my 3rd full tank after that happened and have been putting 93 gas and have replaced the sparkplugs to see if that would help but it didn't. Thanks.

You know I doubt that you are having any residual effect from the cleaners. They should have worked through the system by now. Have you noticed any pinging of the engine? I don't know how familiar you are with timing of a car, but checking the timing could offer a possible solution.

Well the engines not missing if thats what you mean by pinging. Its not making any noises either. Its sputtering alot. Its only when at a full stop and the cars on drive where the idle goes all crazy and wants to shut off and sometimes it does. Its very annoying. Like I said I got auto zone to read the engine light and they said it was reading fuel to lean.
