I installed new mechanical gauges and a afr gauge. While removing the old electric oil pressure sender i hit my wrench on this black cylinder part (attached picture bc i dont know what it is called), then sparks and smoke flew (i didnt disconnect my negative battery terminal). Got everything installed...
Ever since then, I hear a high pitch (singing) noise coming from the passenger floor board where the pcm/ecu is located. My battery/charging light is now lit up on the dashboard. I replaced the battery and the alternator, yet the charging light and pcm/ecu noise are both still present.
When i drive the car now; step on the gas hard, the car runs lean until about 4000-4500 rpms and then the fuel mixture goes rich and then the car hits and pulls so hard.
I feel like i might have fried the ecu/pcm and that is why is has the singing noise. Do I need to replace the ecu/pcm or can i get it reflashed at the dealership?
