seriously, this is getting annoying..., more fuel injection woes. Options

ok, so I think I tracked down the reason I've been burning up head temp sensors.
checked the ground strap & it was in bad shape, so I bought a stock replacement & added another ground further up (behind the bell housing to bare metal where motor mount bar bolts)
it ran great!
....for about a week.

now when I heel toe downshift hard at all, the thing loads up & tries to die on me.
If I put it in neutral & give it a good rev it clears out (ton of black smoke) & runs like nothing ever happened

I'm not sure its the head temp sensor cuz its acting a lot differently than the last time.

I'm getting REALLY frustrated with the electronics on this thing.
if this keeps up I'm just gonna carb the damned thing & deal with it running shitty when I take trips to different evevations.

anyway. anyone have any ideas?

it has new grounds, new head temp sensor, newer cap, rotor wires & plugs

thank you in advance!

The CHTS is only for warm up ,after the engine is warm, the system ignors it. If the CHTS is bouncing back and forth within the relm of reistance that the F.I brain notices it, it could cause this prob.

A faulty ground should not ruin the CHTS, they are internaly grounded.

Heat maybe causing it to go bad.

Have you checked the CHTS to see if it's bad?

have you checked the MPS for vac?
