Yet more problems.. Sudden power drop with CEL + beep?

Hi Skid. That is what is making most sense to me (with my very limited knowledge)

The issue is so spazzy and erratic that to me it seems somewhat electrical and not mechanical.

The thing I really don't get is why the heck the car isn't communicating, at the very least, the fact it's patently running rich as hell. Like what is going on with those sensors and that reporting???

I get there may "not have been enough" misfires (I mean, I've probably felt about 20 in about 8 miles / half hour of driving) but cmon, surely the o2 sensors should be sensing something isn't right here??

Unless the car is telling me the ECU(s) have basically just stopped communicating?

In terms of checking wiring "intactness" is this something a sparky can do..? Checking for continuity (or whatever the technical term is) or are we ripping out carpets and essentially ripping all the wiring out to inspect?

In my head I'd quite like it if someone could attempt to diagnose anything electrical in my drive, or is that not realistic?

 

Thanks for that I'll check this next. I might take photos to see if anyone else sees something suspect.

I had some kind of idea though..

How about I try a full ecu reset. What would these three outcomes perhaps tell me:

- nothing changes at all (misfires from cold idle and straight away driving)

- the condition seems to "go away" for more than say 10 miles

- the condition vanishes completely

Please can someone elucidate what these different outcomes may suggest?

Thanks!

 

I would really question the brain function of someone that thinks

A) taking a car to a specialist for repair in a lockdown is actually even halfway viable? Believe me, I have asked. But most are either not operating or busy as hell

B) it will be a perfectly elementary process to just sell a high-end sports car (with issues) in the middle of both a pandemic and a financial slowdown

I'll just leave that there
