I think I must have a different issue. My tick just sounds like an exhaust leak (sewing machine) when I use moderate throttle, such as trying to accelerate up a hill. Turning or braking doesn't affect the tick I'm experiencing.
The tick on my truck sounds like an exhaust leak when it's under load. One thing I've found, which I cannot explain, is that it goes away almost completely when I run higher octane fuel. Has anyone else tried running a full tank of premium?
