Car has service engine light on on dashboad indicators.

Car start fine, when gas given for pickup it chokes little and runs smoothly, again when stops or slows down
at speed bump or red light it chokes little when gas is given.

Another problem not sure its connected to above issue is air condition works only at full speed 4 doesn't work
at slow 1,2 or 3

Please let me know what problem i have with my car.

Hi jayjillella,

You would need to have a scan done to retrieve the trouble code for the CEL indicating. Autozone provides free scanning services. Let me know the EXACT trouble code.

The blower not working on speeds other highest indicates a fault with the blower fan motor resistor or its wiring circuit.

P0171 = Fuel System Lean

Possible causes are :
1. Intake air leaks.
2. Defective front HO2S
3. Defective injectors.
4. Exhaust leaks.
5. Fuel pressure incorrect.
6. Lack of fuel.
7. Defective MAF sensor.
