several times multiple warning lights flash on the instrument panel, the tach,speedo stop registering and there is a faint click when they switch off- there is no timing pattern to this occuring
The constant is the MIL stays on throughout.

Hello, my name is ***** ***** I'm here to help get your problem solved. What codes are you getting? Thanks.

Have to go to a shop that can read codes
The last time he said it was 0456-that is the mechanic who replaced the O2 sensor and turned off the MIL light on dash. I am in Manhattan Nyc so I habe to find an Autozone or equivalent to read codes

If you turn key on-off-on-off-on within 5 seconds code should display on odometer. Let me know, thanks.
