I have a 1999 3.9 V6 Magnum that is intermittently stalling when I pull up to a stop sign or red light. Rpms will drop to about 200 before it stalls. Normal idle is between 600 and 700. It does fine just slowing for corners and such, but when hard brake, it stalls. Just replaced TPS and IAC, still having trouble. Also, brake and ABS light randomly come on, as well as hesitation when shifting from 1st to 2nd and 2nd to third. Anyone have any ideas?
