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.

double check all your connections. sound like your fuel injector wireing is mixed up.

i had that issue. i was flopping like a fish, too. 5S injectors are a bitch to get to though.

it could also be valve timing.
