Why does my Chevy Lumina APV die when I accelerate, or have transmission trouble?

Short answer: A Lumina APV that dies when you step hard on the gas usually has a fuel or sensor problem. One 1994 owner with the 3.8L found a cracked crank sensor and low fuel pressure, and it still died under hard throttle afterward, so a member pointed to the engine computer. If you're shopping for one, expect high-mile vans to need transmission work.

Symptom: It dies while driving, mostly when you push the gas hard, then restarts right away. The check engine light may come on. Or the transmission slips or shifts badly on a high-mile van.

What to check first

1. Read the trouble codes before replacing parts.
2. Have fuel pressure tested at the rail, under load if possible.
3. Inspect the crank sensor for cracks.
4. Check the transmission fluid level, color and smell.
5. Look for leaks at the transmission cooler lines, which some vans were recalled for.

Likely causes

1. Crank or cam position sensor. These sensors tell the computer where the engine is in its turn. A 1994 owner's codes pointed to both.
2. Low fuel pressure from a weak pump. The 1994 van had under 10 psi at the fuel rail. A new pump brought it to 35 psi.
3. Engine computer. A member suggested disconnecting the battery to reset the computer. If the problem goes away for a day or two, the computer may be bad.
4. Worn automatic transmission. A member said minivans of this era often need a transmission rebuild between 100,000 and 150,000 miles.

Is it safe to keep driving?

A van that dies when you accelerate can stall you while merging or crossing traffic. Fix it before regular driving. Verify with a mechanic.

DIY or shop?

Mixed. Sensor swaps and fluid checks are DIY. Fuel pump, computer and transmission work are usually shop jobs.

Recalls, bulletins and complaints in plain words

• Related recalls: NHTSA lists these recalls touching this area of the Chevrolet Lumina APV: 96V015000 (1992-1995 model years, transmission oil cooler line); 07E021000 (1996 model year, certain aftermarket fuel pressure regulators). Check your VIN at nhtsa.gov/recalls. If your car is part of this recall, the dealer fixes it for free.
• Plain words: Recall 96V015000 covered automatic transmission cooler lines that could separate when the van is driven in low gear, leaking fluid. Fluid on a hot exhaust can cause a fire, and losing fluid can ruin the transmission. Recall 07E021000 covered certain aftermarket Delphi fuel pressure regulators sold in 2007. Run your VIN to see what's open. Verify with a mechanic.

What owners report

• In 94 Lumina APV 3.8L dies under acceleration on Car Talk, a 150,000-mile 1994 APV with the 3.8L kept dying, mostly when accelerating. The owner replaced a cracked crank sensor, then the cam sensor, then the fuel pump after finding under 10 psi at the rail. It got better if he babied the throttle, but still died when he hit the gas hard and restarted right away. A member suggested disconnecting the battery to reset the computer and said a bad computer was possible.
• In 1995 Chevy Lumina APV - Transmission problems? on Car Talk, a buyer looking at two 1995 APVs with about 130,000 miles said both sellers mentioned the transmission. A member said minivans of this era are known for transmission trouble and to expect a rebuild somewhere between 100,000 and 150,000 miles.

Quick tip

Get the fuel pressure checked while the van is working hard, not just at idle. A tired pump can pass at idle and fall short under load.

Safety / mechanic note

If you see transmission fluid dripping near the exhaust, stop driving. Verify with a mechanic.
