Help Odd RPM gauge spikes + Hazzard flashers

[Micksta77]

Hi, im trying to solve a problem with my VS Commodore. The other day when driving to work i noticed a rough start in the morning like it dropped a cylinder though after a min it went back to normal. About 3 mins into the drive to work i noticed the RPM gauge flickering erratically and the hazard light flashers coming on for no reason, then all power cut off to the car and stalled. i tried to start it but nothing.... i let it sit for a min or two and it fired up pretty rough again, i hamerd it back home and left it there, it was still caring on with the RPM gauge n hazzards lights flickering. The cars is an X cop car not a chaser, V6 only if its any help. So if any one has had this problem or know what it is could i please have abit of info on it.

Cheers

Mick

I had the tacho jump all over the place when i got mine, I just got a 2nd hand L2 cluster from wreckers for $20 and it went away,

sounds to me more like you have an ECU issue though if all the problems are related, have you checked error codes?

Yeah checked the error codes i get a 12 which is apparently normal.
