Car being Gay? fuel pump recently installed
okay on my 99 civic si i had a FMU for my fuel management and everyone told me to get a new fuel pump, so i bought a new walbro 255 fuel pump and installed it and for awhile it was okay(about 1 week) and then i come over too my friends house because i heard air leaking out of my car so i tighten up my crappy home depot charge pipes and i was driving it and it was fine and dandy and then im driving along and my car starts to stutter??? it idles perfectly adn then when i press the gas it like sputters and then the rpms go up and then when it goes back to idle its like sputtering, what could that be, is it the new fuel pump, spark plugs???

that sensor is soo fragile that if you touch it wrong the neck breaks off.

walbro 255 too big, but not your problem...

Re:Car being Gay? fuel pump recently installed
stock fuel rail and fpr ? could be rich at low rpm causing it to stutter then go.

Re:Car being Gay? fuel pump recently installed
how much gas in the tank? i've heard the walbro being picky when getting low in the tank...also could be rich if it's not the fuel level.

i have the same problem but i have a stock fuel pump, i dont think your problem is running too rich, my car works best when its not warmed up and the air fuel says its rich and then when its on its way to warming up it sucks nuts and then when its up to operating temp it works good. Might be ignition
