Review on ACDelco 25186687 Original Equipment Ignition by Michael Custodio

My car had a random cylinder misfire code. I first replaced the rather old spark plugs but that didn't solve my problem. Then I decided to replace the ignition. Here it is! I saved a few hundred dollars by doing the diagnostics myself (you can get an OBDII car for $20 - they charge you $80 from the mechanic). Replacing this part is much easier than with spark plugs (fewer fasteners are needed). The car has been running for a few months now and so far so good.
