I always tell everyone I am not an expert before I say anything, so please keep that in mind.

I was told that the correct way to add refrigerant is to pull a vacuum for some period of time and then add a specific measured amount, by weight, of the correct refrigerant. I was also told that measuring pressures, high or low pressure side, is not an accurate way to determine how much to add. I was told that the low side pressure is an especially poor diagnostic, which is what most DIYers do in their driveway.

For me, it is only about $60.00 to have it done correctly at my Indy.

I think it might be like always going back to that same bad relationship with an ex girlfriend.
You feel you love them too much, or you are just too stupid to know any better.
