Stall after a sudden stop - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Daytona#3895 · 10-21-2011, 07:56 PM

My truck is an 87 with a 350 tbi. Coming home from work the other night, a deer jumped right out in front of me. I locked up the brakes and the trucked stalled. I have had a bunch of older carburetor cars do this because of the float bouncing around, but never a fuel injected one. The next day I sprayed for vacuum leaks around the base of the throttle body and at all of the ports. None found. I scanned for codes. None found. It also wants to stall on a cold start as well if I immediately put in gear. Any thoughts?

Wow, glad that you were able to stop it in time.

The only two things that come to mind. When was the last time that the fuel filter was changed? Could be some crap in the filter.

The other possible thing, perhaps you experienced a vacuum leak from the brake diapragm.

torque conver clutch if you have overdrive or a 350c trans can cause that.thats all i can thinks of

Should have stated that its a turbo 400. It fired right up like nothing even happened after it stalled out. I also had a half a tank of gas so I don't believe that the fuel sloshed in the tank. Was only going about 25-30 mph as well. Possibly something electrical cut out causing the stall?

Sounds like the TPS. I've had it happen twice, with the same symptoms.

I dont mean to jack ur thread but my truck does the same thing. Mines a 78 with a 4.1 straight 6. I stoped at a red light real quick and my truck started to studder then it died.

Did any of you guys have your cluster out recently? The speed sensor is attached to the back of the speedometer. Green box with small optical eye at the end of a wire. The eye plugs into the back of the speedo. My truck did the same thing for years--Very annoying when you are plowing snow.

This only pertains to fuel inj. trucks.
