Did a plug and wire job last night on a 93 Z. TR55 plugs gapped to proper depth. and Spirocore 8mm wires. Car smells like rotten eggs real bad and has real bad hesitation in all RPM range.
All the Opti wires are connected as are the plug wires themselves.

Thanks for reading

 

The most common thing that people do is get the wires mixed up.

 

Damnit!!!! That was the problem damn wires reversed.....
Thanks bro appreciate it!!!!
