Hey guys I tried a search but really not sure what I was even looking for. I posted a while back that my car has this hissing noise at idle like a tss tss and is completely inconsistant so its hard to link it to anything. I notice when i rev it up, the noise wont happen but when the rpms come back down, instantly the tss tss is at its most intense time directly after. Someone said it sounded like the injectors playing catch up. Does this sound logical to you guys? Becuase also last few mornings when I start her up and drive, when I give it gas it feels like its going to cut out like its starved for gas for about 5 seconds or so, then finally it goes fine. Does this sound like these 2 could be related both having to do with injectors? I have an 03 auto with 50k. Thanks.
