No brakes in the morning. It will definitely wake you up more than coffee.

Is it a bolted system . If so CAREFULLY try tighten it . If it does not tighten , you may have to replace the O-Rings or sealing washers , after the system no longer contains refrigerant . But when you open the system , do so quickly , put it back together then use a vacuum pump to evacuate it to a hard vacuum , I would run the pump for a couple of hours . Shut it down and valve off the gauges . Let it sit for another hour or two & see if you loose vacuum . If you do , you still have a leak .

No leak , charge it by weight with refrigerant . ( Probably R134a . ) Should be a sticker under the hood that tells how many ounces it holds .

If I can be of assistance , email me off list - WyrTwister@hotmail.com .

What about the other engine codes , did they show up again ?

God bless
