Hi I am new here. I have an issue with a 2002 mustang gt. It is making a chirping sound and a funny smell is coming up from the left rear of the engine comp. close to the fire wall. It kinda smells like a burning electrical. rescently it had an idle problem, so i cleaned out the idle air control sensor and It runs alot better but now this new chirping and smell prob pop up. I also recently replaced two plug boots because of misfiring, no more misfire. If anyone has any ideas it would be appreciate.
