: wacky idle problem

i need some help with my 2002 225 TT. at idle, my rpm's drop to about 600 and then jump to around 1300. this used to be sporadic. i changed my spark plugs and that seemed to fix the problem for about 2 weeks. now, it is running the same way all the time. the check engine light has come on twice for running too rich. if anybody has any ideas and can help, that would be greatly appreciated. thanks, danatt
