2005 dodge neon.?
2005 dodge neon?i have this dodge neon when idleing at a stop light it will lower from 800 rpms to 500rpms and rough idle. no ck engine light and after last oil change it is running rougher. always do the oil changes at the dealership since if anything goes wrong they will cover it under the warranty. it only has 15,000 miles on it. it overheated on me at 3,000 while i was on the hwy doing 80mph i stopped asap. and put the wrong antifreeze in it and they had to clean out the gell and redo the right antifreeze.could the overheating be the problem? what to do?
