First, I'd check the usual culprits, make sure your plug wires are in the right order and hopefully you have vacuum leaks covered.

Where is your air temp sensor located, if it's unplugged or not getting the right info, it will be way rich in a limp home mode, same with engine temp.

What are you using for ignition, SDS, MSD, stock or other? If you are using MSD or another brand of multi-spark system, changing magnet position below 3K usually has little effect unless under load.

What is your MAP reading while it is running?

Hybrid or standard TPS?

Which MAP sensor are you using, 2 or 3 BAR?

Any other options, if so, are they hooked up?

What is your RPM timing at 500,750 and 1000 RPM? I'd put these 3 at 20 or 22, then increase by two for each range, until you reach 36, then carry that to redline, leave the default ignition load values there for now.

If everything is correct and while all the other varibles are the same, you should be able to adjust the mixture with the knob and get it to act right.
So, this tells me something else is probably not right.

Also check your TPS, if this isn't working, strange things can happen, go to 3rd gauge mode and make sure it increses as the throttle is depressed, also check that the value is greater than zero when the throttle is closed.

As far as startup and engine temp values, you can't rule any of that out until you can get it to idle.

Don't drive it until it will idle and starting reasonably well is nice too.

You can mail me, also check out the user board, link below.
