the car sometimes goes dead when at stop sign or light. codes read bad fuel tank pressure sensor
(1) Answer
codes never identify a bad part just a failed system. the pressure sensor is part of the fuel pump module.
i would have it checked by a shop with a scan tool that can read the voltages under a bay test to verify.
the stalling is not related, that is another issue.
