are air bags connected to vacum problem

Hello, an air bag concern is completely separate from an engine performance issue as illustrated by an illuminated check engine light. The check engine light should be diagnosed and concerns should have troubleshooting performed. A vacuum leak is only one possible cause for a check engine light. Clearly, we don't know what diagnostic trouble codes have been retrieved here, so it's impossible to know how to guide or assist more. If you are not happy with your current mechanic's information and testing, then seek a new one - see this link.
