On a long trip, I turned my car back on and the speedometer was no longer working. The mileage stopped ticking over. Sometimes the speedometer needle acted crazy then stopped again. Then the other day, car lost power as if it was going to konk out. Any clues? 1997 Honda Accord
You may have a sensor not communicating from your transmission to your ECU (main computer). If this is setting a hard code in the computer leaving the check engine light on, you can visit your local auto parts store and have them read your ecu for those fault codes to further diagnosis.
If you have a mechanical odometer that physically rolls and not digital you may have a disconnected speedometer/odometer cable. Have a certified technician perform an inspection.
Sounds like two different problems you are having.
First. The speedometer, sounds like an electrical problem.
Second. lost power. Do you have any engine lights coming on when you car felt like it was going to konk out? In both situations, You need to have that looked at by a tech that works with electrical wires and does diagnostics. Check out the askpatty.com site for a list of shops in your neighborhood.

Hello Annie- it sounds like an electrical system problem - most likely with the ECM or the power feed to it - have it checked out by a reliable automotive electrical shop- hope this helps- thanks Super Girls Auto.

You could have an electrical problem or a Powertrain Control Module (computer) issue. The only way to know for sure is to bring the vehicle to a trained automotive technician and have him/her perform some diagnostic testing. If you are having trouble finding a reliable technician, check out the list of female-friendly shops on askpatty.com.
