Hi, any ideas on why my instrument gauges become erratic as the day temps start going up. All good first thing in the morning.
Coolant, fuel, speedo and tacho go berserk
Thanks

Could be the electrical portion of the ignition switch is failing, has that ever been replaced?

Not as far as I know, second owner for past 12 years. Is it an easy repair if it is...

Check camshaft position sensor plug and tap it while running.
