Review on ECCPP Replacement 610 00109 Oldsmobile 2002 2009（Pack by Luis Harper

Ok I really don't like to write negative reviews but it is necessary. I was working on my 2003 Chevy Trailblazer LTZ 4wd in my garage when the postman came through my driveway and delivered my package of new AC Delco Iridium spark plugs and 6 packs of new ignition coils. So I said to myself, while I'm already under the hood, I might as well take care of these other issues. Long story short I finished the job and started my truck and wow the truck was shaking like I was on a roller coaster. The check engine light came on and started blinking, letting me know I was about to explode, you idiot. I parked my truck, grabbed my code reader and said p0300 which means the computer is telling you the misfires are coming from everywhere and I really can't pinpoint the exact problem. So I replaced the new coils with old coils that have over 200,000 miles on them. And low and now the whole problem is gone. Look folks, keep the factory OEM hardware or pay the price every time. The OEM coils in my truck are Delfi and they only sell them individually for between $70 and $100. Replacing all six is expensive, but it will be a good waste of money. Life lesson learned here, be careful boys. Update: I decided to put some dielectric grease on the ends of the coil and now they work great.
