So I believe through my minimal knowledge and research, and attempting to use common sense, I think it's the EGR temperature sensor circuit malfunction. Not sure exactly why, just makes the most sense to me. That's why I got you guys to help me keep this J running!! Any one have another idea?

Have you checked the codes ?
I see the CEL is lit.
Not sure why the Tach is stuck.

Yes, codes are P1401, p0325, and p0500. i guess I'd mainly like to know if one is causing the others to fail? Which would be easiest/cheapest to fix first? I've been reviewing the Manual codes, just not sure where to start, thanks.

Looks like they are independent of each other
Speed sensor, located on transmission
EGR temp sensor or EGR sensor
And knock sensor, very common, just reposition it
