So I have upgraded my TPS with Sacer, as car was pulsating on idle. Forgot to match the voltages during the new TPS install. Can't do ETM sweep test as the "software unrecognized" - software on my TPS is probably too old. Checked both potentiometers - difference is 0.2° between both of them. Car drove way better (still pulsated a bit) for a month, then it started pulsating again, but a lot more than before. My question is, could the pulsating be the result of the not matched voltage during the install?
Also, I have to fill the gas tank very slowly otherwise the pump just shuts off and some petrol spills out. Car is Volvo s80 2001, 125kw.

Forgot to add, the short fuel trim is constantly flactuating on idle (sometimes 10% positive, sometimes 5% negative), but is 0% on high rpms. The front oxygen sensor reads about ~1, but the rear is constantly jumping between 0.1 - 0.8 on idle.
