My 92 with V6 3800 always runs rough and almost stalls when I go into a certain turn on my way home. It seems to happen only when the fuel tank is below 1/4. The turn is a cloverleaf when I exit the freeway. This has been happening for approx. 2 years. Now, the problem happens when I park on a downslope. When I go to pull into a parking space that is on a downslope, the engine starts sputtering and runs rough. Also, sometimes when I come to a sudden stop, the engine does the same. It seems to me that inertia (going around curve or stopping) and gravity (parking on slope) are causing a problem with the fuel delivery. Any suggestions or help of any kind would be greatly appreciated. Thanks in advance Mark
