Hey guys. I'm new to the forum and wanted to introduce myself as well as present a problem I am having. My wife's 2007 SRX has an issue where it is experiencing a rough idle. It starts up fine, then when the RPMs lower to idle it is rough. When I turn on the A/C it vibrates more intensely. I already cleaned out the throttle body but that change anything. The engine mounts are still in good shape. I changed out the spark plugs earlier this year. Could it be the ignition coils? My mechanic skills are a novice but I am willing to listen and learn. Any advice is appreciated. Thank you.
