My Car Keeps Stalling

:1zhelp: my car keeps stalling on me and for some reason it keeps stalling in the same spot everytime, just today i had the fuel filter fixed and it was fine for a few but it was still shaking and felt like it was going to stall then i just had to drop a friend to work and it was going to stall in the same spot it always does thank god the light was green so i pressed on the gas and just kept going, then on my block it was going to stalling again, can anyone help me with what it could be?

i have a 1991 buick century :1zhelp: anyone with any suggestions???

IAC Valve, MAP Sensor, TPS.

check engine light on?

check engine light on? no when it does stall all the lights do come on tho, the car shakes alot and they did just fix the fuel filter and they had said if it keeps doing it then they need to fix the fuel pump :uhoh: when it does stall it's when im going to stop at a stop light and i press on the brake and it will start to jerk then shut off on me...

someone needs to look for vacume leaks too

:disappoin Ok my car keeps stalling i had the fuel filter replaced and then the fuel pump and my car keeps stalling anyone else have any other suggestions?? :banghead:

Oh no, you let those mechanics change your fuel pump, shame on them. Just kidding.

I agree with the previous poster. I would look for vacuum leaks. This can include intake manifold gasket, cracked power brake booster diaphragm (but your brakes would act funny at some point) any and all hose connections on the intake or a missing hose.

Also the rubber gromet/1 inch connector assembly where the PCV valve enters the intake. Replace the PVC valve while you are ion the area. Some folk can do this with the alternator installed but I moved the alternator to get to it.

We had the same problem with our 1991 Century (God rest its soul). We changed some hoses and the problem was solved, easy as that. These guys probably have the right advice on that one!

You might have a torque converter problem. On the side of the transmission there is plug (usually blue) about 5 wires. Try unpluging it and see if it helps. At around 45mph in overdrive the electronic tcc engages, when you press the brake its supposed to disengage. Sounds like that is not happening. It the same as stopping a 5spd in 5th gear with out depressing the clutch. Let me know if this helps

Ditto, You are describing a classic TCC problem. This is a know issue with all GM cars. Good Luck.
