just had engine replaced and it's misfiring on cold start??
Just had my engine replaced about a month ago for this issue, it was misfiring on cold starts. Now it's doing it again, not as bad as before but right when i start it i would say it misfires maybe 2 or 3 times before everything is fine.

What do you guys think?

These cars run pig rich. You will get misfires. Run it at a giher RPM more often.
