My van is currently having issues. First it has been dying during idle not immediately but soon after it has to idle for a minute. The check engine light is on and the codes come out to lean combustion (autozone). When I push on the gas to get up to speed after idle the CEL starts to blink and the van doesn’t seem to be getting enough gas. Sometimes I smell exhaust and sometimes a puff of white smoke come out of the exhaust on starting it. If I’m stopped at a red light it kinda chugs but if I put it in neutral it seems to run a little better. The rpms drop during idle also. If you have a good Idea of what’s going on, it would be much appreciated
RESPONSE
White smoke from the exhaust is an indication of a blown head gasket. This would also cause a rough idle and could cause the engine to want to die. Check coolant level and cylinder compression.
System Too Lean Possible causes
– Faulty front heated oxygen sensor
– Ignition misfiring
– Faulty fuel injectors
– Exhaust gas leaks
– Incorrect fuel pressure
– Lack of fuel
– Faulty Mass Air Flow (MAF) sensor
– Incorrect Positive Crankcase Ventilation (PCV) hose connection
