Thread: WTF?! My tach went out.

Ok, I'm just cruising at 60, and the tach drops with a stutter from the front. No problems on the ~5 miles past that. What would cause this to happen? 158k on a 2000 Grand Prix GT, no internal mods or power adders, just a DIY open cone. I can fix any problem that arises, so I just need to know what would cause that failure. Any advice is openly accepted.

could be a crank sensor. it may start to randomly stall out on you too.

did the tack come back to life when restarted?

I haven't restarted it yet...that's not good tho, I've heard horror stories about the CPS

best bet if your going to restart it. restart it at home were all the tools are lol i know that not much help but save you from having to get it towed home

Ok, well I'm currently 20 miles from home so fudge.

they seem to act up for a good long while before they leave you stuck.

most of the time you pull over if it stalls out, and it will restart.

Ok, wish me luck, I'll update in 30 mins or so when I leave here.

best of luck

Ok, thank god, when I went out to try and start it, it reset and came back to life. I'll definitely be doing my tune-up soon then, and replacing the crank sensors.
