1988 Pontiac LeMans Value Leader 4Cyl1.6L - Preventive Maintenance
The engine coughs and stalls out, what could cause this?
We just got the oil changed and changed the air filter. When you first start to accelerate it hesitates and jerks.

    Defective accelerator pump diaphragm can cause it. Also check the condition of your fuel injectors, PCV valve and its hose, fuel filter and spark plug.
