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.

OK. Ruled out a few things.

Compression is good in all 4 cylinders.
Hooked up the smoke machine to vacuum system- no leaks.
Checked the timing and it's perfect.
Garage told me our vacuum piping is all in the correct places.
EGR not stuck open.
Plugs and wires all good.
Dizzy and wires all good.
Injectors worked great on last motor, and all connected correctly to my knowledge. Plugs just go straight across the wiring harness, 1 2 3 4, and match perfectly with where their respective injectors are at.

I'm not getting a CEL yet. I've driven it for about 30 miles. Just poor performance, occasional stalling when I press the clutch to release rpms on the engine, and rough idle.

Almost has to be a sensor of some type eh? But as I said, they all worked on the old motor. It actually ran better than this one, and it was only holding about 60 lbs. of compression in cylinder 1.

Hit me.
