Asked in Dodge and Plymouth Neon
What is wrong with your 1998 Plymouth Neon if it chugs when you start it and the check engine light just keeps flashing and not giving a code?
I would have your computer recalibrated and find the source of why it got messed up in the first place. Also a slipped timing belt and bad head gasket will also cause that very same problem. I race these little cars so i have a pretty good idea what would cause allot of problems with them. If the check engine light stays off during normal driving i would definatly look into the engine timing and or head gaskets.
