2000 Accord SE, 4 cyl. 2.3 VTEC. I've got just under 120k miles and it seems to be idling rough. But no error codes or check engine light. I replaced a very dirty air filter, and put new Bosch OEM plugs in. It seems a little better, but still a little rough. Could the rough idle be an indication of clogged injectors, or a bad air flow sensor? Also, 750 seems low to me. Shouldn't it be 850-1000 rpms? Could there be a problem even if the CEL doesn't come on? Heavy highway driving (60+ miles per day)since January, mostly city driving for a year prior to that.

I used to have a palm pilot that had software for a VW to read EC's. Is there something equivalent for a Honda? I still have the cable with an OBD II connector.

Thanks,

750/800 is avg

Just use the screw on top of the TB and open it up a bit more, it'll raise your idle - but don't go to extremes, just adjust it a little bit

 

AutoTap, Auterra, and AutoEnginuity offer palm based systems, I have the original version of Auterra. It works okay for basics, but I also got a Genisys
Here's a link for you ;

As far as your rough idle, try cleaning the throttle plate area with a toothbrush and Berrymans B-12, also spray out the screen on the IACV.

 

Does anyone know if there are any software tools like this that work on Open Source platforms?

I'm tinkering with swapping my PC over to Linux, but not if I can't run diag. software.

TIA,
