Throttle lag

[likibow]

Hi my explorer 06 recently had a fuel pump change so i thought this was gonna fix the problem i'm getting a bad response with the throttle it has a huge lag and then the car goes, injectors have been cleaned new fuel pump cleaned throttle body and still does this any suggestions?

TPS= Throttle position Sensor! Any check engine lights or other mechanical issues? Did you have this lag before the fuel pump was changed? Did you also replace the Fuel Filter?
Did you clean the Mass air flow Sensor?

Yes I did have this issue before the new pump, also check the tps cleaned the mass air flow sensor and about two weeks ago I changed the oil and filters so everything is in order

also I have the revs going crazy here's a video of the revs i think all of this is linked together

Ok a few more questions for you.

What is the current mileage on the Vehicle?
Have you replaced the Spark plugs and or Wires?
Do you have any Check Engine lights on at this time?
Have you ever had any check engine lights in the past? If yes what for?

142000 km the spark plugs and wires are about a year and a half months old motorcraft check lights non in the past yes oxygen sensor bank 2 replaced it and no more check light

Yes, it can. Do you have a soft brake pedal, or does it slowly go to the floor if you hold the brakes on?

 

[likibow]

it's soft not completely, today I've been listening and the vacuum sounds clearly under the dash never paid attention to it but when i step on the brake pedal it the vacuum sound goes away and comes back on drive or idle.

a friend of mine works at a dealership and told me that my problem was the positive and negative wires that goes from the battery to the starter solenoid and alternator and the ground from battery to engine and chassis don't know if it's true any suggestions?
