I had the same thing happen last summer and never resolved it... seems to happen only when its warm/hot outside.

From a stop or low rpm, when i give it some gas it feels like its bogging... itl backfire 1 or more times and then go back to driving normally....

i have no idea what is causing this.

i changed cap/plugs/wires/rotor last summer and it was still doing it
also changed a o2 sensor at the same time

any input would be appreciated, thanks.

 

Any mods?

What spark plugs are you using?

 

only mod is a cone filter adapter

plugs are stock honda replacement

 

just throwin it out their as a possibility. fuel pump possibly...?

 

if it were the fuel pump.... i would think it would do it at high rpm and not <2000

 

Does it happen when the car is cold, warm or either?

 

Check/clean your IACV. You may also want to try cleaning the EGR ports, if you have a lot of miles on the engine.

 

only happens when its warm outside and the engine is warm... the egr port was blocked off to try and stop this from happening... obviously i hasnt helped

 

Is it throwing a code? That might help narrow it down a lot...

 

last summer it was throwing a code that stated system too rich or too lean (i think it was 43)

 

FPR? maybe? I'd at least test it to rule it out.

 

how would i go about testing the FPR? and i cleaned the IACV last summer as well

 

bump... more help needed and thanks to those who have stated their opinion

 

help....
did a compression test the other day this is what came out 235-227-225-226

 

Those compression numbers are pretty decent and I wouldn't expect that to be the problem. If it's only happening when the engine is warm, then you can pretty much narrow it down to things that are temperature controlled. I'm not 100% sure, but could include things like FITV, IACV and EGR to name a few. If you haven't actually cleaned the EGR ports, that would be something to try and is cheap.

 

to clean the egr, do i just dump some carb cleaner in the port and scrub? ive cleaned the iacv last summer with no change

 

No, it's a whole lot more involved than that. Here's what I was talking about:

k seems lot more time consuming than cleaning the valve :S but i will see whay i can do.

thanks
