My check engine light had been on for quite some time now, I had the code pulled when it first came on and it indicated that I needed to replace the air idle control. I just got around to replacing it myself this last weekend. After replacing everything I had taken off to get at the air idle, I started the car and began to notice the idle is much higher than what it was and as a result pulls very hard as I am driving at low speeds such as through a neighborhood or parking lot. I have looked into it a bit online to try and find a resolution to this issue. The best I could learn and find is that I need to do a air idle volume relearning procedure, or adjust the idle speed adjusting screw. I've been having difficulties finding specific instructions for my cars year and model and thought it would be quicker and more accurate to actually speak with someone about my specific problem. Do I need to do one of these two things or both, or is there something else all together? I have a basic working knowledge of what I'm doing, but am lost when it comes to troubleshooting like this. Any help would be greatly appreciated, thank you.

You will likely need a professional level scan tool to be able to do the relearn process. DO NOT try to adjust any screws as you will create a whole new problem.

The other thing is that the IAC may not have been the problem in the first place. Just because you have a code involving a specific component does not mean the component itself is the cause.

Ok, thank you. I realized I bit off more than I could chew this time as I started working on it. So I should just take it in to a local shop to have them do all the fine tuning?

You have to be careful about what local shop you bring it into. Stay away from the chain stores. Find an independent shop that specializes in engine performance.
