Has anyone experienced a faint hissing/whistling sound at idle on cold start? It goes away after driving for a bit. I don't remember hearing it last year, but I don't think it's the bypass valve either since everything is functioning properly.

Hey guys. I skimmed this thread but there's so much info to cover, I'm not sure where to begin. Looking for some advice on some troubleshooting.
Quick details:
So, I get the tune from Delicious Tuning with confidence. The tune is good, but during the datalogging process, I definitely noticed some hesitation between 2k-3k RPMs (the bottom of the power band I presume) After many revisions and more datalogs, DT says they can't find any reason to believe it's the tune. The car and power delivery is fantastic after 3K rpm, so I don't have any reason to not believe them. Especially considering I'm a complete beginner and they're the experts. Nine-ish months later, the hesitation is getting bad and I have CELs. P1170, P117B, and P0172. The car sometimes lurches under very gentle acceleration between 2K and 3K RPMs. It also nearly stalls sometimes when coming to a stop. I replaced the O2 sensors thinking they may be going bad. The car is great for about a day, but after a few more drives it seems to have come back. Part of the problem is how much difficulty I have recreating it. Some days it seems fine, especially once the car is up to temp. I'm really not sure what to check now. I'm wondering if it's the MAP sensor? Injectors? Would that really only affect low RPMs and low throttle? I could take it back to my mechanic, but I'm pretty sure he'd just take it back to the tune from Edelbrock and go from there. I'm pretty sure I backed that up before switching to the DT tune, so I could probably do that myself if I wanted. What steps would you guys take next? |

That sounds like the exact issue I had when running a Dbox - the wiring on the Dbox extension plug going to the MAP sensor was loose. I actually caught it in a datalog one time. It was worse when thing were cold, when the engine bay would heat up and the terminals expanded a little it would work fine.
Check the pins to see if they are loose, you can grab a new TMAP sensor for like $60. If it is a wiring/sensor issue you will get it on the Edelbrock tune as well. You can try loading that back up and see what happens. |

Possibly dirty direct injectors staying open. Mine were really bad at closer to 60k miles.
