It was an issue before new plugs and wires. I added a CAI after the new plugs and wires and the throttle body looked good during the installation. MAF was also clean.

Haven't thought of that yet. I'll check it out and report back. Thanks for the advice.

Hello Everyone! I am new to this forum so if this issue has already been addressed, please forgive me. When I searched for the problem I'm having it yielded over 25k results so I figured this would be quicker. I own a 2005 Silverado 2500HD 6.0l 4x4 with a little over 107k miles. I purchased it at the end of April 2020. It started to have this issue about 2 months ago. After getting off the interstate, the motor idles rough almost to the point of stalling. I can put it in park, turn off the motor for about 10 seconds, and crank it back up and idles perfectly. My normal interstate ride is 6-7 miles. I set my cruise control at 79mph. I changed the plugs and wires 2 weeks ago. Anywhere else I drive, no issues. It only happens when I get off the interstate. Any help would be greatly appreciated.
