chase20

i drove the car for about 2 weeks and it drove great. it eventually started misfiring at low rpms and shakes while cruising. if i'm into the gas you can hear valves rattle and sometimes its like it has a rev limiter. now the car wont charge itself and i have put 3 new alternators and 1 battery in it....what's going on with this car? please help!! trying to sell it so i'm desperate for help.

where can i get a wiring schematic for the chassis portion? i'd like to trace the wires to make sure they're good but don't know where some go. i'm having trouble finding a dealership with one that. anyone have any ideas on how to fix the car or atleast get it to charge itself again? i'm begging for HELP...PLEASE!!!!

thank you
