Why does my Evo sound like a machine gun?
It ran rough at low RPM, started fine, idled fine. After about 5 minutes at 3000+ it sounded like a machine gun until I would back down. Also may not hurt to ohms check or even swap out the plug wires. I had a weak foward cylinder one that drove me crazy for a while.
