ok. here is the run down. i recently bought a 1997 Bonneville SSE with 137,000ish miles.

on the ride home if i had to break quickly to a stop the engine would stall. it would beep 3 times, display a check gauges prompt, then id lose all power. no power steering, power brakes, engine just dies.

i can turn it off and start it right back up without any problems.

ideas?

i dont know much history about the car sadly so i cant be too much of help.

Check the crankshaft position sensor, and the electrical system. I used to have that problem on occasion, and that was the cure.

Easiest thing to check is your battery cables, make sure they are clean on both ends. Make sure the battery is secure.

I had the same problem and it was my crank sensor, I got it replaced and all has been good. I hope that helps you out. Let us know what you find?

ill let you guys know what i find out. thanks a bunch.


it sucks having to throw in in neutral and restart it in the middle of rush hour traffic.

It also sucks having to throw it in neutral and restart it in the middle of the highway. In the rain.

Most shops will do it for around $200. The part itself costs $25 and is a few layers underneath your right front tire.

something i could do myself? i really cant go a day without a car unless i waited till a sunday.

would this crank sensor effect my gas mileage any?

Honestly..let'* diagnose this a little further.

Check those battery connection. Pull the cables off and literally look at them. B'ville love to corrode.

Next up, how low was your fuel when slamming on the brakes would make it stall? If the baffles in the gas tank have broken free.. sloshing occurs and stalling follows closely after the pump has no fuel to pump. I'm not only a member, I'm the president

I've had nearly every problem or issue possible with a 97.

Currently I don't suspect a crank sensor. And I'll drive over and beat Colin if he doesn't tell you how easy it is to swap that crank sensor yourself. it'* a 15 min job with air tools and three M6 x 1.00 x 75mm (or longer) bolts. Don't assume the bolts are in a harmonic balancer puller kit you rent, because I've never seen them as part of any kit, unless it cost $500 and was from Snap On.

its been over a half tank everytime.

the cables are slightly corroded. nothing like WOW!!.

It'* true. He'* got enough tools to beat and dispose of me without dirtying his good tools. Of course, it'* doable with common hand tools, and a harmonic balancer puller.

As far as your cables go, there'* a great how-to on this very site: https://www.gmforum.com/t278927/

You can prevent some corrosion by using felt washers and/or Vaseline or dielectric grease.
