Fuel shutdowns while on the interstate at between 60-75 MPH. When the problem occurs while driving, I immediately loose power, it goes into a rough idle, and I have to immediately pull over to the side of the interstate. It will either idle roughly with no ability to increase throttle for 5-15 minutes, or, it will stall and I can start it again in 5-15 minutes (when whatever is not working, cools down). This has been occurring since 2014. Our service center has a long history. No proper error message is given through the register storage when tested using gm shop analyzers. Checked gas cap, replaced fuel pump, cam shaft position sensor, spark plugs & wires, crank shaft position sensor, fuel injector, bcm. Have not replaced coil packs and icm yet. (a dynometer is probably needed to simulate load for a moving vehicle. Many shops don't have it because of cost.)

2002 chevrolet impala experienced a problem with stalling and misfiring.***no answer required***. *mr this was an intermittent problem. A hole burnt through the upper intake manifold, resulting in excessive amounts of air to enter the system. The clogged converter was the source of the problem which allowed excessive back pressure to build up in the system and gases that were much hotter than normal entered the manifold.

Dt: engine started to spit and sputter. It got worse. Caller changed fuel filter because the dealer said it might be the problem. While driving the vehicle the car ran fast and tried to take off, and she had to slam the brakes hard, and hold them to t stop car. Dealer said a hole was burned into the manifold, and when they did a diagnostic test, they said a misfire code came up. Problem was with catalytic converter being plugged. Dealer fixed the burned intake manifold before they found that the problem was catalytic converter. That was the only thing wrong with it.

Vehicle fails to start - motor does not crank, starter does not engage. Tests show battery, starter, alternator circuits are good - no error codes given. Vehicle engine runs rough and the gas mileage has decreased considerably. Local mechanic states that general motors is having a problem with the computers overwriting its own code and therefore causes problems, such as this, with the vehicle. Vehicle starts occasionaly at best. Vehicle is unreliablbe - cannot trust it to start when needed. Going to call dealer to check if there is a "silent recall" to correct the problem. Otherwise, will attempt to use the federal safety agency service bulletin #00214a to try to get program reloaded into vehicle's computer without charge though I expect very little help, if any, from a dealer.

The vehicle's gas tank would not fill because air had gotten in the tank. The dealer has been notified. *nlm one must hold the gas nozzle away from the filler tube and restrict the flow. The tire and fuel system/tank/injectors were replaced. There was a rattle sound coming from the engine due to the injectors the vehicle would stall. After the engine is hot, the next time the vehicle would turn over but no start and run rough. The fuel gauge fluctuated(not giving actual amount). The solenoid was replaced due to hanging by the hose retainer. Scc

What is wrong
General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V‑118, 09V‑116, and 15V‑201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
Risk
Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Remedy
The remedy applied under recalls 08V‑118, 09V‑116, and 15V‑201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engine’s front valve cover and gasket. Vehicles that are covered by recalls 08V‑118, 09V‑116, or 15V‑201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number. The recall began on February 19, 2016. Owners may contact Chevrolet customer service at 1‑800‑222‑1020, Buick customer service at 1‑800‑521‑7300, Oldsmobile customer service at 1‑800‑442‑6537 and Pontiac customer service at 1‑800‑458‑8006. GM's number for this recall is 15757. Note: Until the improved remedy has been applied, owners are advised to park their vehicle outside since the fire risk exists even when the vehicle is unattended.

What is wrong
General motors is recalling 1,497,516 my 1997-2003 buick regal, my 1998-2003 chevrolet lumina, monte carlo and impala, my 1998-1999 oldsmobile intrigue, my 1997-2003 pontiac grand prix vehicles equipped with a 3.8l v6 naturally aspirated engine. Some of these vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking.
Risk
If the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and may spread to the plastic spark plug wire channel and beyond increasing the risk of an engine compartment fire.
Remedy
Dealers will replace the engine’s front valve cover and front-valve-cover gasket with new parts of an improved design and remove the engine’s plastic cover and plastic oil-fill-tube extension, free of charge. The recall is expected to begin during may 2016. Owners may contact chevrolet at 1‑800‑630‑2438, oldsmobile at 1‑800‑630‑6537, and pontiac at 1‑800‑620‑7668 or http://www.pontiac.com or http:www.gmownercenter.com.
