Hi everyone,can anyone help me?,I purchased a used car recently,the pass.frt. parking light has never worked,and also the acc. pedal is quite close to the floor, resulting in only using part throttle under the hood,now here is where it gets weird,my local auto zone manager says that because of a bad ground,which is responsible for no parking light,the cars throttle has been acting as a ground,which meant the cable has been heating up,causing the cable to STRETCH resulting in the acc. pedal to sag to the floor? has ANYBODY ever heard of such a claim? please let me here from anybody
