I finished up my swap 😎 but it does not run right...
symptoms
1. Hard starting
2. Idles fine but any throttle causes it to cut out and start crackling (think of a top fuel dragster idling)
3. running very rich I/e black plugs
4. Stinks
5. Throwing p0100 maf circuit p0115 ECT circuit and p0505 iac

A couple things , I spliced the +b wire from 98 into +b 92 plug C1 in doing this it left all the WL wires that were factory spliced with a lead running to the +b pin on 98 just sitting, all of these wires run to the circuits listed above symptom #5 ​​​​​(I believe) I re spliced the wire and it kills the truck. Any help would be prime!

So I got rid of the coolant temp code (missed a wire) still have the others, I'm really wondering about that bunch of WL wires , also fuel pressure, I get 38-42 or so with vac hooked up, 40-45 without but with a slight crackle no crackle and normal rev if I pinch the return until it hits 60 psi, bad fpr? It does change idle pitch when unplugged or return is pinched.
back to the b+ wires, now what wires in the b+ section of the harness go where and what do I splice etc. I'd like to get rid of the codes! (I have a brand new maf, I did the conversion to the new style)

So on a whim I spliced the WL wire from the harness back in with the WR wire from 92 body plug and WL wire from 98 ecm and it cleared all the codes but it ran like garbage? I'm so confused.

Anyone out there in the ether?

So I fixed it! I had to splice the wire in with the other two, and I had a leaking injector

Thanks for posting the fix!

I have not done a 5VZ-E swap so I didn't have any input.
