Dodge Nitro Problem
Drive Trains Affected: 2WD, 4WD
Visitor, 2007 Dodge Nitro, 2WD, 108,650 mi
"Lightning bolt in )( " comes on intermittently , often when accelerating, or applying brakes. Once the light comes on acceleration bogs down in first then surges into 3rd gear, drivability is limited. On open highway at 60 mph vehicle bucks and surges and bogs down until vehicle is under 55mph. Gently touching accelerator causes vehicle to buck repeatedly and only applying more pedal helps but feels completely bogged down. The only code comes up is 0456 Evap Intake small leak detected. sometimes CEL check engine light may come up. cleared with scan tool. There is no predicting when it happens, weather, etc...
