rigt then, i put a rad on the nova 2 days before pvs that i took off my other car just to use, so then i got an m.o.t on the nova as it was running fine then, i drove down to pvs in still was running mint no problems what so ever, then on the way back it started running sluggish like they wasn't enough fuel getting through to the engine, so i disconnected the wires when i got back just to make sure they wasn't any breaks in them, i had to put the rad then back on my other car
