I just changed my flywheel.The stock flywheel had 3 things for the crank sensor to read ,but the new spec flywheel only had 1.Now my car is back firing and it has no low end it just bucks and misfires.My air /fuel gauge does not indicating that I am running rich.When at idle I noticed that it will go rich for a moment .It will go into boost in the higher end without any problems.Is the flywheel the issue or is it some thing else .I changed the idle stabilizer,oe2 sensor, cap,rotor,plug wires,and spark plugs before I had the clutch changed. I changed the spark plugs again after this started to happen, but it did not help.The car was tuned before I changed the clutch and flywheel.Can someone give me some insight please?

The first rule is: Change only one thing at a time, then test it to see if it's better or worse.

Bucking and misfiring indicates a lean condition... perhaps you have a major vacuum leak?

There is 3 reference sensors on my stock flywheel and only 1 on the spec flywheel.This is my problem?Are the 2 that are missing can they possibly be the time reference sensor and speed sensor?

I checked for vacuum leaks. I only changed the clutch , flywheel and after the problem started I changed the spark plugs

Did you set the new flywheel's reference sensor to the same height as the stock sensor? That has been the issue with numerous Fidanza installs.
