Won't stay running

Shakes or Wobbles problem
1993 Buick Skylark 55,000 miles

If I drive above 60 mph for a bit (highway driving) then break to about 10 mph the car will begin to shake and then shut off. It happens at tolls or red lights. I have found that it is less likely to happen if I down shift into drive 2 or neutral when I decelerate to 30 mph and finish the stop in that gear. I have recently had a new alternator, cleaned fuel injectors, and a new fuel filter. Please help!

This car stalls if you come to a stop after
Driving over 35 mph.

There are molded hosesthat meet at a plastic box about 5 inches long and 3 inches high on the intake.

One of the hoses (1/2 inch or 3/8 inch) has a plastic tube inside it with an electrical connector it goes back to the intake.

A 3/4 inch molded hose is attached to the bottom of the box, it goes down some where near the ac compressor.

There is another hose (1/2 inch or 3/8 inch)
That connects to the front of the box and goes to where the air filter is housed.

There is another common size vaccum hose I think it is attached to the intake.

The hoses are rotting and cracked.

The plastic tube with the electrical connector is clogged.

I need the name of the hoses and the plastic tube with the electrical connector.

Part stores have no idea what these parts are.

Where does the 3/4 hose go?

What is the name of the box the hoses are attached to.

I want to replace these parts.

Hello,
Does it start up after stalling then stall again after putting it into gear?
If so, that problem is the transmission lockup solenoid.
A temporary quick fix is disconnect the electric connector on the front of the trans. If it quits stalling, then replace the lockup solenoid located inside the END pan on the trans. Do a trans filter and fluid service while you're at it and add some LUCAS trans conditioner.
The large vacuum line goes to the brake booster.
The others are emissions related.
Sounds like you need to go to a highly recommended certified mechanic.

All of us appreciate the donation.
Hope I've been able to help. VIC

There is a hose (1/2 inch or 3/8 inch) that has a plastic tube inside it with an

Electrical connector it goes from the air

oil seperator to the intake manifold.

This is a 2.3 liter quad four engine.

What is the sensor called?

I want to replace it because it was clogged with oil sludge.

(i traced the stalling to map sensor.)
