My car was running like crap for about a week check engine light flashing and traction control light on code said misfire in cylinder 3 so I changed spark plugs and they were bad but it didn't fix my car because it also needed a new coil pack amazon was by far the cheapest for the gm part which I wanted to get about 50 bucks cheaper than anywhere else. It came on time and once in my car has been running great. Hopefully it stays running good and this part last but so far so good.!!

Just sold my car to a friend who had the car for 2 days , when they phoned me that the engine light was on and car running rough. So they came over scanned the car had a misfire on # 3 cylinder. Part was $320 at napa and $168 on Amazon, ordered it at 4pm and got it the next day at 11:35 am... Fastest delivery ever and car is running as it should.

so fare so good

Purchased an after market one from Ebay that I returned as it was faulty. This original unit worked fine.
