    Do you trust your mechanic? .......Fuel pressure is applied from the PUMP to the fuel lines and ultimatly to the injectors via a fuel rail. Pressure should be constant through entire system , up to the regulator/damper.See service manual for specs applicable to specific model/engine. Mass air flow meter or connections to it may also be an issue.

    We have a 95 GMC Safari and had this happen several times. Seems the Safari is known for burning up a cap and rotor pretty fast! Change the cap and rotor! My husband keeps a spare and has gotten really fast at it! It's really easy, even I can do it!
