i have a 92 hatch with a ls integra motor in it that is sputtering when it warms up.....i have tried putting a different dizzy and replaced the fuel filter (i read that could be the problem) and it didnt help. The car runs great when it is cold but when it warms up and your are cruising at a constant speed it starts to spit and sputter. If you have had the problem or know how to fix it let me know as soon as possible.

Is it misfiring? Check the plugs and tune up stuff. Could be fuel problem, faulty pump, clogged injectors.

 

mine is doing same thing and i cant figure it out either. and ive replaced plugs and all fuel shit.lmk when u find out lol

 

ya it is missing but its only when it warms up......? i just replaced the fuel filter and it has a walbro fuel pump on it with a fmu. i checked the plugs and they all look fine. ill change the plugs tonight and post an update.

 

just changed wires and it didnt help

 

You probably need some type of fuel management system like hondata and a tune. Do you have the right ecu?

 

injectors ??

 

...fmu get a better fuel management chrome or hondata

 

im getting it tuned in the next week on chrome, its boosted now....but it was doing it a month before it was boosted.? the car ran fine for a year before that so i dont think it would be the ecu.

oh and dsm 450's are going in soon

 

i was about to say why are they talking about fuel management? no k swap or turbo. lol but anyway.

did you do a tune up? sounds like it could be a distributor rotor, spark plugs and wires. or maybe clogged injectors or fuel filter or bad fuel pump.

at what rpm is it idling at? two low and it will studder. should be about 750-650rpm. could you try adjusting the idle screw about the throttle body. it is easy see if it has been tampered with b/c they is suppost to be some wax on there that must be broken inorder to adjust it.
