SOURCE: poor gas mileage
Do you have a gas smell in vehicle if you do there check and make sure that you are NOT loosing gas by a leak in the fuel line that was replaced or anyother part of the fuel sytem for that fact. If there is NO leak then the pressure from the pump may be too high and therefore dumping too mucj fuel into chambers but if this is true the vehicle may have a hesitation on take off or may run a little roughand a rich burning smell from exhaust, Check these things out make sure that the fuel pressure at the injector rail is correct refer to your repair manal for exact specs,because I NOT sure what it its, good luck and thanks for using FIX YA

Either the cruise control is going out or the torque converter clutch circuit is going out on the trannys overdrive. Do you have check engine light codes? If so you will need to have a computer hooked up to read them. Darrel coleman also has a problem with his car like this and I have suggested the same thing to him

Try cleaning the fuel pump filter. Under the seat behind the driver lift the carpet and you will find a round cover with six screws remove the cover. The fuel pump is directly below unscrew the retaining round plate and remove the pump. At the base of the pump is a small filter if it is covered in black muck that's your problem. clean and replace. job takes about 10 mins good luck. please let me know how you got on!

It's got all the symptoms of a leak in the fuel line. You may want to start backward at the tank and work your way all the way to the carb to find it but it would be surprising if it was something else. All the best.

my sister had the same problem. There are 2 sensors that can cause this when they go bad. One is the oil pressure switch, which is located near the oil filter. When the PCM reads this switch, and gets a low reading, it will automatically kill the engine. The switch costs around $4.00 and is a 5 minute replacement job. The other possibility is that the crank position sensor has gone bad. When this sensor goes bad, the PCM can't read the appropriate speeds of the crankshaft, and will adjust the fuel and air mixture to compensate, often times the engine will die because it is getting insufficient fuel and air. The Crank position sensor is located on the engine block near the water pump. It is around $40.00 and at the most a 30 minute replacement job if you are unfamiliar with the process. I hope this helps. I'm a vehicle mechanic in the Air Force, with roughly 7 years of experience on the floor.
