Ok, I've posted several times here about the K5 stalling at red lights. I took it in for a diagnostic scan, no problems. Anyhow, I decided today for some reason to pop it in neutral while at a light and it didn't stall! So, i played around-and it stalls only when in drive at a stop-neutral no problem. Any idea what the heck would cause this??? Its an '87 TBI 305, with auto tranny.
