Hey I've got an issue while idling. Two days ago I took it through an automatic car wash with under carriage wash. The next day the volts started oscillating at idle and it almost sounded like it didn't have enough fuel. Is it possible the wash did something to the fuel pump, or is this an alternator issue that's separate from the washing. It's like it is trying to stall. The fuel lines looked ok.
Two notes: Last fall the dealership had to bypass the fuel pump relay on the TIPM. Maybe its relevant. Also, there is a chirp very similar to what Erobins described in his thread posted on 1/17/18. I checked the (plunger?) on the IAC, it was black... that's about all I can tell you lol. I didn't take the throttle body off but it looked clean. This is my dd so I'm stuck until I can figure it out. Luckily I don't have to go anywhere really until I take the bar on feb 27.
Here's a video of what's going on. It doesn't really start until about 25 seconds in. Also it might help to wear ear phones. Thanks in advance for any replies!

Let me know if that link doesn't work. It is the first video I've ever uploaded to youtube.
