[QUOTE="03SoCalCobra, post: 1370732, member: 3979"] I have almost 45k on the 03 now. Problem-wise I seem to be slightly ahead of curve, as problems come up on my car, then shortly thereafter the posts start popping up from other people, so I'll share this one and hope I save someone else the pain. I've now had this happen twice, and after some research find out that i'm not the only one.. [url]http://www.consumeraffairs.com/automotive/ford_spark.html[/url] The first time several months ago I was in my driveway, I start it up to pull it into the garage to do an oil change and after a minute or so of idling it starts running really rough, then loud "POP-POP-POP-PUFFFT-PUFFFT-POP" sounds. I popped the hood, thinking I lost half the bolts in the drivers side exhaust header, but the sound is coming from near the base of the blower...and then I see the plug cover trying to detach itself. You know those moments in life you always remember- the one where 2 seconds feels like 5 minutes? That was me between the time I put my hand on the plug cover and again on the key to shut it off. :burnout: The second plug back from the front on the drivers head had backed itself out- completely - and was being held against the open hole by the plug cover and coil pack.
