Updating Spark Plugs is n 383 stroker

it’s about time to get some new plugs in this truck

My Holley Fuel Injection looks like it’s running rich and occasionally stalling

So time to swap out plugs and if that doesn’t fix it then maybe it’s a bad O2 sensor

Old plugs are AC Delco R44LTS

New plugs are NGK TR5TX or #7397

We’ll see how she runs

Change the plugs and drove it from Davison up to Houghton Lake doing 85mph almost the entire way besides having to stop once for fuel. Drove it all day Saturday on the trails without any issues. Drove home on Sunday doing around 80mph with one stop for fuel. No issues…..

Now yesterday (Tuesday) I started it up and its missing real bad. Smells like fuel.
