Hi.. I'm new on here but have been looking on here for years. Thanks for all the info so far. My question is on a 2013 prodrive with the ecotron efi. It has prodrive e5 but the heads are illiowa marine. Runs great when gets warm but when first cranking it up it only runs on one cylinder for a few seconds and then the other side kicks in. Seem like it's worse when below 40 degrees.
Any suggestions will be appreciated.
