For the last 3 months my 93 3.4l keeps stalling, when ever you are coasting for a while, mainly in the middle of intersection's when you coasting through, and i also a engine code once and a while which comes up esc, but goes off after a few mins, i changed my coil pack, changed my ecm with another one i had, and still the same, the car starts right after it stall's, its just really starting to piss me off, any idea's?
