If you're having engine problems, the issue is likely related to the fuel injection system, not a carburetor. You'll need to troubleshoot the fuel injection system, which might involve replacing components like fuel injectors, fuel pump, or sensors. To find the right parts, you should:
* Check your owner's manual: It might list authorized repair shops or parts suppliers.
* Use online auto parts retailers: Sites like AutoZone, Advance Auto Parts, NAPA Auto Parts, or RockAuto will allow you to search for parts based on your Alero's year, make, and model. Be sure to specify the engine size.
* Visit a local auto parts store: A knowledgeable parts counter person can help you identify the correct parts based on your car's details and any symptoms you describe.
Before ordering anything, carefully diagnose the problem. Incorrect parts are expensive mistakes.
