Sounds like a fuel issue. If you can, pull the injectors and check the o-rings to make sure they are good condition. When you pulled the plugs, were they wet with gas? Do you have a fuel pressure guage? If so, check the pressure from the regulator and compare it with specs. Are the plugs gapped to .044? Is it really cold where you are? There's alot of factors here, hopefully you can narrow it down a bit. Good luck!
