Fired up my car this morning.
Immediately, I noticed that it was making an odd noise, a high pitched whine, which would raise pitch with the RPM of the engine. Turned out to be my radar detector. I shut it off, and all was well. I chalked it up to my radar showing it's age.
A mile later, my head unit shut off on me, but turned back on. This kept happening the more I drove, and it began happening more frequently.
I always have a CEL in my car (since I don't have an EGR), but it caught my eye today...it appeared as if the voltage that the LED was receiving would vary, causing the intensity of the light to fluctuate constantly.
To top this off, when I would let off of the throttle, the car was still getting fuel somehow (even after I pulled over and unplugged my extra injectors). At anything below 3000rpm, I'd still run between a 12:1 and a 15:1 A:F ratio with my foot OFF of the throttle.
Weird.
My gut tells me that this is a grounding issue. Anyone have any input on where I should start looking? Does anyone have a grounding diagram of this car?
edit: Note - a similar episode happened once before with my stock head unit a few months ago. My head unit kept turning off, and my radar detector made the same noise. At the time, those were the only symptoms I noticed.
