I have a USDM 99 ITR in my civic, and recently when under 4000rpm or light throttle, theere is a sputtering, coughing, and when in neutral the car will slowly die. It starts back up, and evrything seems fine, until you go underway again. Wondering if it would be the fuel filter or the injectors to replace, or if it would be anything else. On the way home, I bought injector cleaner, and it helped a bit, but the coughing and sputtering is still present, but not as much. thanks

 

you might not be getting enough fuel

 

i agree get a new fuel filter and also what ecu are you running? is it tuned?

 

i would check everthing filter pump injectors

 

it is all stock. Stock computer (p28) but running through a VAFC, but with no changes as of yet.. I bought the car the way it sits, and havent had a problem until now. Where is the fuel filter, on the line or is it attatched to the sump? So along the line or in the tank? thanks

 

also another question for a first time honda owner. what is the rubber hose off of the back of the intake manifold. it has been blocked off, and a cansiter has a line cut, looks like same line, and other side of canister( by firewall) connects to line underneath car, which is by, or is the fuel lines.

 

thats probably the evap canister

 

what is the evap canister used for? good to hook it back up or no?

 

?

 

yes, get a helms and hook it up STAT!

 

i recently took the vac line from the intake man to the fuel pressure regulator, and replaced it. the sproblem has seemed to go away.

 

**** 100km's later, started doing it again.. lol.. eventually i will figure it out.. unless someone can help me before i eventually stumble on the right answer lol
