Running rough when cold, good when warm Heads/cam ls1, car has been tuned to run in speed density. Has a brand new battery, sensors all around.
Starting to have problems when cold, will have a hard time idling/getting going. I'll lose electronics, won't want to rev. When the car is warm it runs perfectly with no hiccups.
No constant codes but it did through a few the other day. Ive cleared them and it hasn't come back but the issue persists.
Codes were P0106, P0121, P1115, P1637. Ive checked all the body grounds and they look good. From what I can see the grounds on the back of the head are good.
Little lost here, any suggestions? Thanks all.
