Codes P0339 and P0300 pop only when engine is cold.

Question

I have a 2007 Dodge Caliber. If I start the engine cold I get codes P0339 and P0300. If I let the engine warm up and reset the codes it will then start without any issue. I have replaced the battery and the CPS, neither fixed the problem.Thanks.

Answer 1

P0339 Crankshaft position sensor intermittent

P0300 Random misfire

From what you are describing check the sparkplugs, if there is a underhood sticker that call for a specific type of sparkplug you may have to use that.
