Open Circuit?

[brandonh06]

My 2001 Mustang GT keeps dying on me when i come to a stop and it hesitates really bad around 1500-2000rpms..i put the scan tool on it and it says i have an open circuit on my O2 sensors..I dunno what to do.

Inspect your O2 sensors and look for broken wires or if they've been knocked loose.

What mods have you done? Long tubes?

Do you have a way to datalog your front O2 voltage readings?

Have you checked for a vacum leak?

Open circuit is a broken or loose wire. Make sure the harness is connected and you haven't a pinched/broken wire in the O2 circuit.
