A/C and heater problems

[DakotaExplorer]

A/C wasn’t blowing very hot, my friend who’s more experienced in A/C said we should add Freon. So we did and as we were putting it in, the engine started to slow down and almost die then click and go back up while idling. The words of my friend who, knows more about A/C since I’m clueless says, it’s the A/C compressor turning on and off, it also does this while the heater is turned on. I was told to add more Freon but looked at a few posts and now I think I’ve added too much. Anyone else have an idea? Thank you!

You need to get a pressure gauge and a temperature chart so you know what the pressure should be at the outside temperature you are testing at.

So a gauge that has say red yellow and green labels and then numbers isn’t universal?
