I replaced both the power steeriing belt and the drive belt for the engine and now my 2000 odessey is running like crap and missing.

SOURCE: 1995 honda odessey runs rough in drive and worse when ac is on .

One thing to change right off is the fuel filter. If its running rough it could be a few reasons but that definitly needs to be changed if it never has been. Depending on the transmission, I would have a service done on that.
