Question: my car cranks up then after 30 minuets of running I starts to here a ehisping sounds?Poag1 / Apr 17, 2025
Hi Ozell, I'm glad to assist you. That sound could be a vacuum leak, not an issue with the spark plugs. It will affect idle, and fuel economy, and cause rough running of the engine. It is best to have your car diagnosed and checked by a professional mechanic. You can go back to us for the exact part you need once the mechanic recommends that part you need to purchase and replace.
