Does anyone have the low-side/high-side/rpm specs for an '02 dakota air-conditioning system. I charged my system to the factory amount but it is still acting erratic. I prefer not to use generic specs for the readings and would prefer to use the factory specs. Any help is appreciated. Thanks

Not sure but it always varies with temperature. The hotter it is outside the higher the head pressure.
Good rule is 35 back pressure at about 1500 rpms, with a cold suction line at the compressor.
If you weighed the charge in by the factory amount specified, it should be right on.

The way I do them is I charge to 35lbs. then I race the motor to about 2000rpm's, if the compressor cuts out I add a little more gas. Repeat until compressor stays running.

That'll work too Menis but, but if you add too much......, you really nead to check the head pressure too. If your condenser fan isn't coming on you can have a big problem if your head pressure switch fails. Ever see a refrigeration hose explode? Not pretty.
