2002 V70 FWD 2.4L - RPM problems

[LiThiuMElectro]

Update on the saga of the Volvo, I quit driving the volvo because the problem was occurring at low speed not only the highway anymore. So I sat patiently and waiting for the contactless ETM, not a lot of time to work on the car work etc... Got the part Yesterday and I started to take everything apart took a while so I had to finish today.

So today I had pretty much all the connection cleared up from the hard goo that covers the contacts inside the ETM. The only thing left was to cut the long bolt, clean the hard goo a little bit, install the contactless ETM and solder everything.

SSSSSOOOOOOOO yeah.... did all that and now the car starts, rev up super high then die... The car is just like "Fuck idleing I don't understand what this is anymore".

The ETM makes a high pitch noise, I can hear the flat open and close for the self test?

Here's a video of the rev up https://youtu.be/C0v2kh0r01s and some not soooo clear of my jankie soldering.

If ANYONE have any idea they are welcome...
