Rough idle

[LastSVXintheChi]

so i read through the unstable idle thread and his problem sounded similar to mine but there was never an answer to what fixed it...when the weather went cold this week my car started to idle rough at lights and when it was in park after it warmed up...it runs fine at speed or if i keep my foot on the gas...today i let it sit to see if it would die but it wouldn't it would get worse and worse then the rpms would go up to 1500 and it would be fine then it would start to bounce again and repeat....

i cleaned the MAF but that didnt work...i unplugged the MAF to see if that would make it better but it was even worse...someone told me to change the fuel filter cus idk when it was changed last and it is only $25 from NAPA

any thoughts?


i forgot to add that i took it for highway blast at about 80mph for 45mins or so and when i got off the highway and had to sit at a light it seemed fine
