Problems with ground after engine swap & adding headers
Has anyone experienced Issues with their car after an engine swap & replacing stock manifolds with headers?
Having some issues, high BLM, poor idle &misfire as well as low power.
Any experiences with these kinds of issies coming from poor ground?

Re: Problems with ground after engine swap & adding headers
A poor ground can cause a multitude of wierd issues. Double check your battery cable to block connection and cable to chassis. Next, check the cyl head to chassis connection. If those are good move on to the harness to head(s) connections. Front the factory, 3rd gens use studs to hold the ground rings on. These work loose at the cyl head and can cause a weak ground, esp as oil impregnates the threads
Issues with the O2 sensor are common after installing headers. Check out a heated sensor
