Very Poor Performance (Partially Solved), Just replaced 5sfe and having problems Options

[joeladam02]

Story: Just replaced my 5sfe (lost compression in cyl. 1) with another one that supposedly has 100k on it.
Rebuilt entire top end. Brand new plugs, wires. All sensors transferred from old motor in working condition.

Symptoms:
Car won't idle steadily...very rough miss.
Has no power. Absolutely no bottom end.
When I am cruising at high RPM's and press the clutch, the engine stalls.
Also stalls every time I come to a stop sign or try to slow down and turn in somewhere.


Any ideas?
I've checked grounds, plugs, wires, timing, vacuums, sensors. Dizzy worked on old motor. I'm flopping like a fish here.
I haven't gotten any CEL's. Haven't had a chance to test compression just yet either.
Please tell me the bottom end of this motor is not bad too. That will make 3 bad bottom end 5sfe's for me if it is. And I will probably drop a stick of dynamite in the car if that's the case.

what made me look into the injectors wa the fact i had an obvious miss at idle, so i unplugged each plug wire to see what cyl it was, and each cyl i unplugged made it worse. so it wasn't a actual misfire, it was a huge reduction of power/efficiency in the whole engine. so out of curiosity i swaped my injector wires around and BAM, engine ran great
