alright.. i need help. heres the deal. my 89 Legend Coupe stalls from time to time. my RPM is around 700-800 when idling in drive.. thats not a good thing.. i just had alot of engine work done, radiator, new alternator, new oil filter.. and so on.. seems its a battery problem. other than corrosoion on my battery heads.. i would have other problems where sometimes everythign electrical would shut off when i try to turn over the car. i woudl remedy this by reattaching the wires to the battery and not having them on so tight.. i figurea battery problem is the cause of the low rpm and stalling.. but i realised when i tightened the wires on the heads today.. my radio cut out on me alot (cd player with car kit) . . not a good sign.. so ... how can i fix this? is there a possible short in the wiring? (reason i had to replace alternator, car ran after replacing alternator however).. or what ? any help would be appreciated..
