Review on 🔥 Enhance Ignition Performance with the Cardone 84-1830 New HEI Electronic Distributor and Module by David Underberg

I completely tuned my truck in December and it worked great for almost 60 days. With a light load and highway speed, it then developed a slight wobble. This jerking got worse. Assuming the Cardone manifold is good (I've had good luck with them in the past), I've tested every sensor I've replaced over the next few weeks and they all passed a good test. I checked the EGR and everything is ok. Replaced MAP sensor, no change. Put the old distributor back in place and the car will run MUCH better. Plugged the Cardone back in, checked the sync and it worked. It is clear that the distribution is bad.
