86 4kq saga

Problems: intermittant high speed stall, tack insanity, and now a low speed 
stumble AND idle fluctuation.

With the list's help I replaced the fuel pump fuse and relay, and identified 
a bad wire to the coil. I also sourced some BG44k cleaner for the injectors. 
Now the stumble and tach issues need help.

The tach cuts out completely and then jumps up and down. I assume that this 
is a wire short from the distributor, but I have no other ideas. The stumble 
is a brief, but very annoying stumble that seems to happen intermittantly. 
My local lad says that it may be a bad tps printed circuit, but it seems 
like that would happen more frequently.

Finally, just this evening for the first time I had a bad idle fluctuation 
and rev and stumble. But it went away after literally a minute. Is this 
related? Or a new issue. I cleaned the ISV a month a go. (It is actually 
warmer, 32f than it has been for a week..)

I would just drop the car off, but the problems have been very sporadic, and 
I live 160 miles RT from the dealer, and he won't give me an awd loaner.

Any ideas? (Car has new hood cable, 
cap/rotor/plugs/wires/oil/pads/hakas/euros/h4's/filters/rt-fr-cv/lt-fr 
bearing/, needs new h2o pump lifters and belt.)

Thanks!
