Review on AUTOSAVER88 Ignition Compatible Trailblazer Colorado by Juan Lukas

Okay so I bought a set of spark plugs when my truck started misbehaving and it's been a while since the facility thought there is a problem and it isn't. The problem was 2 defective coils. I ordered them for next day delivery as I needed a truck urgently. They came, I installed them and found the truck was working harder than before. My son quickly learned that a little pressure on the top of one of the spools would improve the truck's idling. I decided to remove everyone's thick rubber boot, tension the spring a bit more, reinstall and reinstall the boot. That helped. The truck drives as before. I suspect this might be the problem some are having, but if so, it's an easy fix. I would put 5 if not for that.
