So for the last couple month's my car has been extremely slower. I can put the pedal to the floor and it slowly goes up then jump's up in speed. My cat's checked out fine, i have recently changed my spark plug's so those are new. I was wondering if this happened to anyone else? I have 117,000 mile's on my SE and i don't know what thing's the previous owner changed out. I know it's a V6 but before all this happened she rode great. I will be happy to add any info i missed i just don't know what else to add.
