Why does my car sputter every now and again when my a.c. is on and I'm going about 60mph? It only does this 3sec rumble when the ac is on and I'm going over 55mph
The ac put,s strain on motor,even at this speed,have you changed plug,s and wire,s lately?
No..I got the car about 6 months ago and it's always done this.
Change plug,s and wire,s.
All of them,spark plug,s to start,then if it continues,change the wire,s.
