I just had my expedition serviced for change oil and an engine wash, after taking it home and filling up it with gas, it suddenly lost power, when I step on the gas it doesn't accelerate like it was choking it only resume its normal rev when I release the gas pedal. The mechanic told me to replace the fuel pump he said it doesn't give enough gas. The car right now doesn't have a problem starting its only when I drive the car in first gear or accelerate that the rpm goes up and down.
I replaced the fuel filter and it was really dirty, cleaned the air filter and just a while ago changed all the spark plug and they are all worn out. The car still shows problem accelerating from time to time when ever I step on the gas and sometime it would accelerate but the climbing up slope coming from the first gear it feels like the engine wants to die out but it would gain control again when you release the gas pedal so there's no power at all.
also it has some vibrating sound now after everything done. Should I change the fuel pump now as earlier advised?
