eh guarantee it is a free fix. Locate your thermostat ground and sand the thermostat housing and wire connector til it's kinda sorta shiny. Then see if your symptoms still exist when it is at operating temperature.


*When ever something weird/odd occurs with your electrical system on a honda clean that ground before doing anything else. If that ground is dirty it can present itself as a bad ICM, bad tps, bad coil, and some other weird sh*t...If need be add an 8awg ground off the housing to your passenger side frame rail..it'll help keep those issues from appearing again.
