Hi, I'm new to all this so be gentle....
. I'm not sure on how to post or thread. My wife has a 2002 Echo, check engine light came on. I read in here to clean the MAF sensor, I did that but I'm not sure it's clean enough (the wire is coffee colored). Disconnected the battery which reset the light. At first it ran rough on start up, now it idles rough.It runs well when the peddle is pushed.
