I wonder if anyone can offer some advice? I have an 87 RR (3.5 efi/auto) bought 4 months ago. It would misfire on the freeway and sometimes stall at idle. I discovered the alternator and PS pump belt tensions (wear in the clamping bolts/washers etc) were both slipping and so the belts slipped. Now I think I have the belt tensions right the motor runs better than it ever did before, but the motor still misfires with lights and the aircon both on - it's ok with only one or the other though I suspect the aircon is taking more power than the lights. I have never had a car before, in which belt tension was critical. Is it a known issue or is it possible something is taking more elec power than it should or it's a possible alternator fault? Battery is fine and alt light behaves normally. It is often fairly hot here (West Australia) and air conditioning is nice, even at night. TIA
