Any assistance?

Hello, I own a 2003 Alfa Spider 916 with a 2.0 JTS engine. I've noticed some issues with idle and acceleration, especially when the engine is cold. Additionally, after revving, the engine almost stalls before recovering. I used the Multiecuscan tool to check Lambda sensor voltage (see attached results). Can someone confirm if these figures are correct? Unfortunately, I couldn't find short-term and long-term fuel trim values on this tool, but using the Torque app on my phone, I observed very high positive values for both bank 1 and bank 2 long-term fuel trims. Any assistance would be appreciated.

Ignore anything the Torque app tells you, listen to what MES is saying.

First thing I would check for is air leaks in the air intake piping.

Then disconnect the MAF and see if that makes any difference.
