Car starts hard and throttle response is way off

[cody]

My 92 talon is currently having some minor problems. Its starting real hard when its cold. Once its started when I push the throttle theres about a 2 second delay before the car actually accelerates. When it warms up the throttle response goes back to normal and the car starts easy. When its warm it runs and drives great. I thought coolant temp sensor for the hard starting so I changed it with one I had laying around but that didnt to anything. Tried a different ecu for the throttle problem that didnt fix it either. Any ideas? Thanks.
