Hey guys I drive an 06 tC and I was curious to know if a hissing sound out of the injectors is normal or not. I drive it everyday and ever since I bought it the injectors make a little hiss like a turbo's injectors i'm assuming and is this normal or do I have to get it looked at?

 

Hiss = intake.

^ Yes, intake (or air) hisses

Injectors = clicking; not hissing. You're hearing something else. Hissing is fine if coming from under the hood, normally its just air

 

Lol people tell me my car sounds like it has a turbo under the hood

 

The hiss sound is louder if you have an aftermarket CAI intake.
