I was traveling on the highway and lost power. Vehicle will now due 10-15 mph. I checked the fuel pump and filter, they are fine. Air flow meter???? Any help is appreciated.

 

does it idle rough? do you smell gas? does the idle speed jump up and down in drive? sounds like something with gas pressure regulation. Regulator migth have gone out..spark plugs could be bad..along with spark plug wires....just my opinion..hope you find some help..good luck
