Have you checked for OBD2 fault codes via the diagnostic connector under the dash in front of driver? Do that first.

SOURCE: 91 camry starts and shuts off when put in drive or reverse

I was an ASE master auto tech for 13yrs and have seen this problem before. It sounds like the idle air control valve on the intake manifold has stopped working and the idle speed is not being controlled(letting the engine idle too slow which causes a stall when put under a load such as putting it in gear). Try giving it a little throttle while putting it in gear if that works let off the throttle if it dies you will know the Idle Air controll is not working.

SOURCE: on a 2006 chevy impala it tells you to tighten the gas cap

There is no sensor for a loose gas cap. What is happening is that the evaporative emission system is sensing a "Large Leak". Usually code p0455. The computer sees this as the most probable cause is a loose gas cap depending on several factors it looks at. You would need to clear the code(s) and see if that was the problem. If the light comes back on, then you have a problem in the system that will not let it seal. Possible solenoid problem, leaking hose / line, etc.

SOURCE: 03 jetta shut off while driving.

Check the load reduction relay. I had this happen twice and repaired twice on my TDI mk IV. It throws no codes and almost has to be witnessed by a mechanic to be believed.

Have a 2001 chevy impala runs great on acceleration but rough on idle engine light is on gas milage is down replaced plugs and wires wondering if i have an issue with the oxygen sensor

your check engine light will give you information that will help solve the problem-get the computer scanned, go to a retail auto parts store, they all do it for nothing. Write down the actual codes, and come back here with the codes, you will get the help you need.

Car is stalling

My 2001 chevy impala was stalling at the light or when I was just riding down the road on the highway it would all of a sudden just cut off. I had a mechanic change the crankshaft position sensor and the car have not stalled or shut off since. Hope this helps you and good luck.

I have a 2006 Chevy Impala LT 3.5 L, and if I drive the car, the fan under the hood remains on, even after the car has been shut off and the key has been taken out. It stays on for about 2 minutes, then...

It's suppose to. The fan will continue to run after the car is shut down to cool the radiator down before a timer shuts off the fan. I also own an '06 Impala LT with 69000 miles, and the coolant has been "disappearing" Since there isn't any excess water coming from the tailpipe, I'm figuring it's the water pump, due to the noises it makes (think marbles in a beer can). Be safe and check you coolant level. Hope this helps you!

MY 2002 CHEVY IMPALA 3.4 DRIVE FOR A WHILE THEN SHUTS OFF

Sounds like an altinator problem. Have it checked out. If your altinator is bad it will not recharge your battery while its running and cause your car to lose all electrical power. When this happens, your car will not usually run for more than 10minutes or so.
