1996 Grand Am dies when i slow down

What color is the smoke?
Black means running rich.
Gray or white is coolant
Blue is oil.
This shounds to me like a fuel system issue. Injectors might be bad

Hi could be your idling speed needs adjusting slightly

Could be a sticking idle air control valve, or dirty throttle body.
The computer uses the valve to control idle speed by regulating the amount of air into the intake.

Check for vacuum leaks on all hoses underhood. Make sure all intake componets are intact and they are tight.

Is the check engine light on? If so, get to an auto parts store, they should pull the codes for free.

Sounds almost like a bad throttle position sensor. The computer uses the TPS to help know when to shift on this car if I remember right, and if the TPS is bad, it can cause that jerking. Along with the car dying when slowing down after driving. But check everything else out first. Including electrical connections.

take a little time to check the air/fuel filters and spark plugs if you have not done so in a long time. all of those things will cause the van to stall at light or stop sign. replace all items that need replaceing. a little service work will keep your van running for a long time.

Check out your cold start choke. It is designed to cause your fuel mixture to run "rich" until it warms up. It is basically a heat sensitive coil that reacts to heat from the exhaust manifold.

Shell has had issues with contaminated fuel in the past cant recall what it was but it actually damaged the fuel pump. I hope thats not the issue here can get costly in some cases fuel pumps on GM are a whole assembly. DOes the gas gauge still read properly? This was a big tell with the contamination last time. Gauge would read empty even when full.

My 2000 Grand Cherokee had the same problem, without all the sputtering, it would just die approaching a stop. We could only keep it running by slightly pushing down on the gas petal when coming to a stop. I replaced the Throttle Position Sensor, but that didn't change anything. A new mechanic I found replaced the Idle Air Control Valve, and we've had no problems in a week.

a number of things is ck engin light on

i think your exhaust might have a leak which is heating up your oil when this happens the engine suffocates and wants to die.
