I received the codes 1441, 1351, 1361, 1371 on my Snap On Scanner. For 1441, it recommended checking the EVAP Vacuum Sensor for charcoal granules, which I found and cleaned out. I am tempted to replace the other parts which the codes recommend, but I think I'm hearing a hissing/leaking noise by the driver side of the engine by where the fuel lines come near the throttle body cables. Can anyone relate?

 

Several codes are often the result of a bad alternator. check the output of the alternator to see if it has too much AC. That is, the diodes have broken down. Set the meter to AC and put one lead on a good ground and the other lead on the output of the alternator. If the reading is above 0.03VAC, its time for a new alternator. AC causes the PCM to go crazy. If it is bad, replace the belt and the tensioner too.
