I live in MI, it snowed like hell this morning. The truck started acting funny like it had no power. When I left work today the check engine light was on with a 0299 code, it's about 70 mile drive home and was lucky to hit 65mph. I couldn't figure out what was wrong until I opened my airbox and the filter was covered in snow and ice. I thawed everything and let it dry and it still has no power. Could it have gone in limp home mode? or could something else gotten screwed up because of this. I checked the turbo and it looks clean and spins freely. Any help would be appreciated.
