HI im in need of some help!the past few weeks my 95 integra rs had some trouble accelerating but last night it got dramatically worse. the motor started to sputter very bad and had no power at all even when floord and would kinda back fire and then almost die. now it sounds like i have a miss in my exaust. I have just changed cap, rotor, wires, plugs, and fuel filter. and still the same! now would this be a bad O2 sensor? please help!!!

 

Check the MAP sensor, my car had the same problem. Have you check the codes?

Maaaaaaan. I am having the same exact problem in my first gen b16 Ef!! HOLY ****. This is driving me crazy. I dd my hatch to and from work/college and i barely make it there and back. It began sputtering and bogging/backfiring right when i pulled up to the cross walk at school haha. thats my luck -.- but anyways. I changed my spark plugs, spark plug wires, fuel filter, no vaccum leaks, my fuel pressure is running around 34 usually which seems to stay constant. But i cant find out the problem! I'm about to go crazy. If we can help each other solve this problem in anyway, let me know lol
