Why is when I push the gas it acceleration is slow

Hello, sounds like some kind of engine performance difficulty. This will take some diagnostic testing to resolve - in the following areas: 1) Fuel delivery 2) Ignition spark 3) Air coming into the intake -- either restricted or too much 4) Exhaust flow restricted 5) Engine timing concern 6) Engine compression concern Is there a check engine warning light illuminated? If so, testing can start there to find out what trouble codes might be present, aiding with clues as to where to start looking for your problem. If not, each system I listed must be tested to see if it is working properly. A well trained technician with a good diagnostic tool that has data monitoring capabilities and a shop manual to use for reference will be able to get to the bottom of your concern with little difficulty. www.repairpal.com/repair-shops
