When hard on the gas or running up steep hills i tend to get a crackly noise coming from somewhere behind the dash it sounds. The best way to describe thhis noise is almost like a wire vibrating or scratching under the hookd.....noise is directly related to throttle.....doesnt happen all the time....mainly like i said when i go up hills or am hard on the gas....my old man says he thinks its prolly the injectors....any other ideas?

 

Could be. try putting better gas (93 octane) and run that for 2 tanks. It sounds like it may be spark knocking....
