Swaped em....pulled plug wires and still the same. Gunna test voltage at connectors and pull resistance at the injectors....and go from there

Really sounds like a coil to me, especially since it got cranked without the coil wire attached or grounded

I have a spare around i think......

check to see if you have spark, check to see if injectors are clicking.

Im getting spark.....

If its starting and running its getting spark, check the primary and secondary resistance with your multimeter. Sometimes when they go out they will still deliver a weak spark at idle and then run normal at higher rpm. I just had this happen on my friends Mazda, it would idle fine, run like dog crap with any more than 10% throttle, then run perfectly normal above 3000rpm.

Well...here is what i got....both injectors have resistance in spec....the wiring for number 3 has voltage to both sides...where as wiring for number 2 only has voltage to one side.....nothing in the manual about voltage going to just 1 side or both.....weird thing when they were removed i had my throttle response back.
Ok....so listened to the injectors....1 and 4 sound great. 2 sounds really weak...wasnt able to listen to three....too far away.
Cleaned tb and iac...that helped a bit....i have some idle hunting now...ita quite obvious...lull in motor with a sharp hissing sound from the tb. Keep trouble shooting i guess

dang that sucks that your car is down

How about the missing VSS, is there a vacuum leak there?

I still have a few places to check....mostly everything topside is good....need to check the looped evac system and all yhe ones on the underaide.....hopefully later today when i have more daylight.

Code 22 anyone? Pulled coolant temp sensor code this morning......at least ive got a cel....

Theres your misfire. Its the one with two wires on the coolant pipe thates above the transmission.

Replaced and still the same.....damn.
So i got a good listen to the injectors....both two and three i can hardly hear the clicking....while one and four sound good.....guess ita time to get some o rings.....too bad im working two weeks through....

You can swap injectors to test them, swap the potentially bad ones with what you think are good ones and see if the problem follows them across cylinders.
Of course a cylinder balance test would also be a good idea.

Pulled injectors....two of them had some sort of build up in them....now to replace and button up

Yeah....much better now.... Low end seems better throttle response back....let the rtv cure and ill drive tomorrow!

So everything seemed fine....when i drove it same issues. Checked my wires...voltage within specs from ecu....suspected a broken wire so tested for continunity....have that....injectors still not clicking....anyone know the resistance for thw wirws that run from ecu to fuel injector?

Word....swapped ecu's and now i have 3 active injectors.....leaves me to believe a wiring issue with injector 3. Time to take readings... again

All injectors firing! Looks like ill be driving tomorrow! Everything checks good....so far.

Drove around for a while....runs smooth now. So glad to be done with this proccess. Now question remains on what to do with the 5s i pulled.....
