95 tracker miss after warm up

[1995 toad]

haven't tested maf used to run great going up hills and wot... would only miss steady state drive ..
ecu out now.. all stock caps.. ordered kit ...don't look bad but will replace
when i pulled in the shop ran great through full rpm range cold.
its killing me...lol

i forgot blush
new spark coiL?  all else is new but not this. (coils do fail)
if you pull the vacuum hose off FPR there are 2 tests to try easy,
one is with fpr hose pulled and golf teed, so it can now suck air,
this act raises fuel pressure  6psi and if running gets worse,  then we know it was rich and  is more rich now,  we know it is rich misfiring, but if gets better running then we know the fuel mix was way too lean . a very simple and many times revealing test.

put that hose back now . to normal.
test 2:
then pull the front hose on that  front plenum box of intake manifold. there are 2 hoses short. one is fpr and  left of it is EVAP,so
see 2 short hoses.
pull the left hose X front,  this is EVAP hose. at hot idle this will cause lean out, and if runs better implies, engine was too rich.
if it gets worse you have vacuum leak or have bad maf. (or just needs to be cleaned)
the maf is a hot wire MAF  and can COKE up as you drive in heavy traffic,  and when that happens it reads low and EFI fuel mix goes way lean
the ECU will no know this until voltage out is below near dead 0.6vdc. we clean them every 50k miles for sure,  but keep the spray back about 8"inches
to not damage that hot wire,  58B00 MAF is yours marked correctly as that?

ARE  all giant hoses to the MAF to TB all good, no bad gaskets end to end.
My 96 the main huge intake tube up top that PO lost the bolts to the mount there and it beat itself to death, (mount #19 here)
#17 to 21 must not leak.
the mount aluminum cracked off and that huge pipe sucked are like mad. this made engine go lean and no power. (called unmetered MAF air) The whole induction path maf to TB must be checked any time lean is suspected. on any mAF cars, (on 8v it races fast with full power these leaks) but the 16v never acts like that it goes super lean and lost of power, ever idle wants to stall if bad enough.

no air leaks at ISC (marked test) hose nor PCV . (btw good luck to you !!!)

Resistors finally got here... soldered in .. fired up great runs good until warm up then same miss as rpm is added. idles great 
pulled fpr hose plugged vacuum leak ...fuel pressure 41 runs the same.
evap hose pulled... misses the same
cleaned maf  runs the same ... what brand of cleaner you prefer?
will check again for vacuum leaks

no vacuum leaks either...
