Hi all, my prob started about 2 weeks ago. I noticed when sitting at traffic lights the engine would idle normally but every now and then would hit a rough spot for a second then come good. At first when driving along it ran normally but the last two days its starting to get a bit chuggy when driving. Any ideas would be appreciated, thanks in advance.

Try cleaning the MAF, IAC and throttle body
