I left my 97 Prelude SH with 153k parked at an airport garage for a week. Upon starting it and driving it away the following things happened in sequence. 1. Speedometer, Odometer, Tripometer, all the omoters were not working. (Tach etc. work fine). Check engine light came on, ATTS light came on. Car seems to run and drive fine.

About a week ago the 1st two elements of my cat came apart and the garage knocked them out leaving the rear honeycomb in place. That fixed my rattling cat and loss of power problem and I have been intending to get a new cat. Could the above problems be related to the ghetto cat fix? Any suggestions?
