Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.

you need to find someone with an old type scan tool,or one that has an adapter for the older cars to read the codes. you can also do this by jumping 2 wires on tha obd connector and count the flashes. the first suggestion is the best. get the code and get back to me and we'll go from there. hope this helps Thanks Ray

Code p0446 is for EVAP vent valve performance. Unfortionly there isn't just one item that can cause this code and the test require the use of a scanner. You can do a visual check but other then that with out scanner its just going to be replace and hope. That could wind up being exspensive.
