Slow acceleration

Wasup guys, i just bought a 2002 maxima. It doesn’t accelerate as it should when i mash the gas. It shifts fine, I’ve cleaned the MAF and throttle body but it still won’t take off as it should. All help is appreciated! Thanks

Have you checked the simple things like a fuel filter, clogged fuel lines, contaminated fuel, etc. ?
