I just got my 3.5 swap done, and now I'm experiencing hard starts in the morning. Like I have to gas it in order for it to start. When I turn the key the RPMS shoot to 1200 then right back down, this happened 3 times, then they would struggle to stay up. I have a heater hose running from the IACV to the Engine and the hose doesn't seem to be to strong since it pinches and whistles when the car is running. What can be causing this? Warm starts and what not are perfect.
