So today I noticed an odd electrical buzz coming from what I can describe as the middle of the engine when the key is turned to the second position. Can't tell where it is coming from but I can feel it on the fuel rail cover. Any ideas what this might be and how serious a problem it is? Did a search here and didn't find anything. It sounds like a bad ground maybe? Car starts and runs fine.
I did reset my oil service lights by jumping ports 7 and 19 at the service plug after changing the oil. Could that have messed something up? I don't know if it was occurring before the jump since I can't remember the last time I had the hood open with the key turned to the acc position. The hum is not audible from inside the car. Thanks.
