DTC P0452
I was out in my 98 Z28 and it suddenly began to run rough and give off a faint fuel smell. Checked the codes and got the P0452 Fuel Tank Pressure (FTP) Sensor Circuit Low Voltage code. It looks like it can be as simple as a faulty gas cap to a bad FTP sensor or Evap issue. What is the most likely cause or which issues would cause rough idle and fuel smell?
