My engine is running rough when cranked. It does not matter if it is hot or cold outside. It does it every time. If I try to push the gas it acts like it is not getting gas. Once the engine gets warm it runs perfect. I think it is a sensor. Any ideas? The engine was replaced 15,000 miles ago. With new plugs and wires.

Engine only runs bad when it is first cranked after 5 minutes it runs perfect. It cant be a compression problem. It would not get better after the engine warmed up. I replaced the wires and plugs recently. Would any of these things you suggested make the engine run bad when cold and then run perfect when engine is warm. IT DOES NOT RUN ROUGH THE WHOLE TIME> JUST WHEN ENGINE IS FIRST CRANKED.
