Hey, need the help of you CFI gurus.
This seems to be a common issue, but found no solution in the archieves.
My 84 Town Car stalls randomly on deceleration or hard stops. Did not do so when I bought it and before I had worked on it (new vac lines, pulldown diaphragm, fixed vac leaks, EGR valve cleaned, coolant flush....)
Runs smooth and quiet from cold start to long drives.
Car throws these codes:
KOEO code: 85 on demand; 14,41 in continuity memory.
85 is CANP
41 is HEGO always lean
14 is erratic ignition PIP
Interestingly enough I donīt have a CANP solenoid. The vacuum purge valve is controlled by the green 3port vacuum valve in the intake manifold (rear to the firewall). One side controls the CANP, the other side the heat riser valve.
