okay so my idle has been kinda wierd. sometimes when at a light the rpms will go way below the 1k (600-700) and it will seem like its going to stall and then it will raise up and normalize

so then when i got home i revved it just a little bit and the rpms will hang a second and then drop below and then normalize is this normal? any suggestions...maybe battery?

doesnt happen always but i have noticed it a few times

 

Clean your IAC, and do a MAP wack.

 

noob here...what is IAC and MAP wack?

 

nevermind search function ftw
