Ok here you go, I have 2007 heritage and replaced battery. its throwing codes air intake temp
sensor high/low and engine temp sensor. I replaced both sensors because codes would not clear and bike ran like crap and would not idle correctly. this did not seem to help as the bike still runs badly. codes still won't clear. Any thoughts on this? Thank You!

I would check the ECM connection for corrosion. You have two different systems reporting bad that are not connected and the only common thing is the ECM. Might want to check negative battery cable for corrosion on both ends. Are those the only codes you are getting?

If you deep dive into those codes, it's a circuit issue, probably not the sensors. Appears you have some corrosion in the connections, loose connections or broken wires. If you are good with a meter shouldn't be too bad finding it.
