I have a 98 200 SX that when it warms up it hesistates when I shift. It will stop whenI floor the gas peddle. It idles fine when warn and has no hesitation when cold. I changed the fuel filter and no change. I check the cap and rotor and wires, they were fine. Anybody have an idea?
Thanks

 

check the your spark plugs cause they might be fouled or the gap is to big from normal wear and tear. if they are new then i would get a noid light and check all your fuel injectors and see if there operating properly cause you might have an injector sticking. also check to see if you have any check engine light codes. you can have autozone check for you for free but they wont delete the code.
