my car has a little hesitation very rarely. usually about 1 time per day, my car will hesitate in the lower revs with light throttle. i have replaced: wires, plugs, cap&rotor, timing belt is good and so is ignition timing. my tach does not bounce when it is studdering. could it be sticky injectors? ignitor?

this is a stock 95 JDM B18C. stock cx fuel pump. no codes. i don't think its the fuel pump because this only happens in low load situations. but maybee?

I don't think that's it... need more details though... ****, it could be a dirty sensor in the fkn IM...

 

if your ignitor is bad the car will not start. If its going bad then it will feel bad at RPM level.

your need to up grade the fuel pump to the stock gsr or better wabro, because gsr had bigger injectors. did you use the gsr fuel line to the fuel filter? it all bigger than the cx...

If it only does it on light throtle, I wouldn't think it was the fuel pump either. What ECU you using?

 

JDM obd1 p72. i have a walbro sitting in my room. i'll put that in and see if it helps. and yes, i am using the gsr fuel line to the filter. i really think it is not the pump though because this has never happened at WOT. what do you mean "if the ignitor is going bad it will fell bad at RPM level"

if it was a dirty sensor, wouldn't i though a code?

which rock have you been under?

CX,VX,DX,LX,EX,SI

RS,LS,GS,GSR,ITR

ALL HAVE THE SAME 250CC INJECTORS!!!!

PRELUDE IS THE ONLY 4 CYLINDER THAT HAD DIFFERENT INJECTORS 310CC

 

i replaced my fuel pump and fuel filter with a walbro 255 that i was saving for boost. and i dumped a bottle of injector cleaner in the gas too. we'll see how that works. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by ace1875 &raquo;</TD></TR><TR><TD CLASS="quote">

i thought the VX and CX injectors were smaller. since they are not, i will swap injectors off a VX engine that i have in the garage if the other changes don't work.

 

The injectors fuel flow(the amount of time they are open) is controlled by the ECU. so Honda used basically same injector CC rate.

The fuel pump is the one that is different in some of the models.

I personally don't like the gas tank fuel injector cleaners, i think they don't help as they have the same compound as paint thinners do. I used a different method (I forgot what its called, its on the tip of my tounge ) well they use some kinda waves, ithink sound waves, to bombard the injectors and break the "junk" out of them.
