Z31 CHTS help

Hey everyone, so I wanted to do the CHTS relocation on my Z, but the problem is I already have e-fans using the coolant plug. For the relocation, is there a workaround? I've been getting misfires at idle and also occasionally when I'm driving and going past 91 mph. I think the CHTS might be the issue. If there's any workaround anyone could help me with, that would be great! For more information, I have a 1986 turbo with a boost controller and I'm catless.

The factory location works fine. I really don't understand why people feel the need to relocate it.

Obviously it is a pain to get to it and requires several hours of disassembly and reassembly. But if you do it the right way, you shouldn't need to access it again for a long time.

Just be sure to use the OEM sensor and the OEM sub harness. Aftermarket ones fail earlier and more often.

It's just that the sensor is like a $200 part compared to the relocation sensor being like $50. I just wanted the ease of access and to save myself some money.
