cold start problems

[sking]

i am having problems with my 914 when the car is cold.after the oil temp raises then the car runs fine.it's not really cold because i live in san diego.when i had the engine out i changed the temp 2 sensor because it was bad.the one i took out said 15 degree celcius and the one i put back in said 35 degree celcius.would that cause the problem?
thanks shawn
