all of a sudden my 93 rx7 13b is starting to idle low, after a 5< mile drive, while sitting at a light my rpm's dip stoppin around 500, it will either go up only to come back down quick,, the car hasnt turned off yet but, this morning the check engine light appeared and then quickly dissappeared, i can almost hear a leak, but im not sure,,, i dont know if its just my nerves freaking me out or what,, my question is in order to locate the possible vac leak,,, what would be the most likely bad lines to search for???

if it was a vaccum leak you would be idling high..not low... check your tps. if your check engine light flashed then a code is stored. go to your diagnostic box and ground "ten" Then desypher the code. (its listed on the newbie section links)

if your check engine light came on, then pull the codes and see what caused it.
