Hi I I need advise my 95toyota camry is idling ruff and the engine light goes off an on

Check Engine Light Flashing usually means a Cylinder is misfiring. Vehicle needs to be Scanned for codes. Some Auto parts Stores perform Computer Scan for free.

Check for loose wires and vacuum leaks. Try having the codes read to get more information on the problem.

If you had the battery disconnected for any length of time, you may have to drive it for a few hours before it goes back to normal. I assume everything was fine before the install?

Lynn....did you ever resolve the issue with this vehicle?
