ok i have an issue,ok my sister has a 95 civic ex with a d15b auto tranny,her car is loosing power,when you floor it it slowly pics up speed ans starts stuttering,so i took out the fuel pressure gauge out of my DA and put it in her car pressure is fine.Distibutor is fine new spark plugs,oil filter and the car has no cel's what can it be???

 

Are the plug wires, cap, and rotor old?

Have you checked the ignition timing?
