2005 Mitsubishi Lancer 4g94 MPI 162800 miles
Mitsubishi Lancer 9 with a 4G94 MPI engine. When the fuel level in the tank exceeds 10-12 liters, during a sharp right turn or hard braking, the engine revs up and down between 500 and 1500 RPM for 2-3 cycles, and then stalls completely. This is ONLY noticeable when turning right or braking; it does not occur when driving straight or turning left. The fuel pump and fuel filters are new, and the tank is sealed. The fuel vapor recovery system is disconnected from the tank; a long, loud hissing sound is heard when the tank cap is opened. If the transmission is in neutral during a left turn or hard braking (the car has an automatic transmission), no problems are observed.
