I uninstalled my Holley sniper EFI and Hyper Spark System. I had enough of issue after issue. Just way too many variables to go wrong. I had a bad ECU first, so, sent 4150 back to Holley , car ran fine for a while, then , lost spark. Sent Hyper Spark Distributor back, got it replaced. But soon as it came back, I sold everything and went back to my reliable Holley Avenger carburetor.

One of Holley install videos you have to mount your o2 sensor after the collector after all the pipes merge together

How is this suppose to be more reliable then a carburetor? I see alot of people complaining about their ecu going out.

Did you notice your water temperature gauge was bouncing back and forth from 100 - 300? You have an electrical issue that could be screwing with your ECU that's outside of the EFI. Electronics are very sensitive to voltage spikes ANYWHERE in the system.

I know my guage cluster has some issues. I've gone and rewired a lot since this video so hopefully any issues that were there are eliminated! Thank you!

Zanes Garage no problem. I installed LED light bulbs for my taillights and I was getting error codes and my cruise control quit working. The LED’s pulled so little voltage it screwed up the ECU so I had to install load resistors on the lights. When light bulbs can take out your cruise control anything can happen in your EFI if your electrical system isn’t at 💯

Hi there, the issue for me turned out to be a bad ECU with the sniper. I was able to contact Holley and send my unit back to them where they swapped out the ECU and sent it back to me. I haven't had an issue with it since. Hope that helps!

Holley does not make sensors, they relabel bosch sensors
