2003 Tiberon, 4 cyl. , auto. --- When I come to a stop and turn off the engine, i hear sort of a swishing noise coming from the rear of the car for about 3-5 seconds , then it disappears. My engine light came on and i had the code read by an Auto Store ; it said possible failure of the 'Evap. Solenoid' (or simular wording) . Is this part located at the rear of the car and is it relatively easy to change ? Thanks much for your help.
Sorry but dont have the actual code number. When the car is shutoff, there is a ssssshhhhhh noise coming from the gas tank area and it lasts about 3 seconds then goes quiet. The check engine light is coming on about half the time ; when it is on, the gas mileage is very poor. WHen the light is not on, the gas mileage is superb. No driveability problems with the car . Any ideas ? Thanks.
You can make sure the hoses/pipes aren't twisted/pinched/restricted. Still, I'd like to know the actual code number so I know I'm sending you in the right direction. If the problem is what I think it is, you're unlikely to find anything visually. Furthermore, diagnosis will require a very systematic approach with a voltmeter attached to the fuel tank pressure sensor in order to verify whether all pertinent components are operating normally.
