I am having problems getting the idle right on my car. Right now its tuned on hondata with a basemap from jackson racing. The car is running stupid rich right now. The car is idling around 1000-1200, but when I rev the car, and then let off the gas, the revs drop down to like 400-500 and seems to bog down, then rises back up. Sometimes it will just stall out. Help!

 

im havin the same damn problem. . .except mine is 100% stock, and at about 2000-2500 it bucks till it hits 3k then it seems fine

 

i have a boosted gsr and i have been trying everything and nothing yet and its doing the same shit

 

ok I used hondata and increased the IACV duty cycle from stock 25% to roughly 80%. This fixed my problem, however, the thing is still running stupid rich at idle and cruising. I don't think its in the fuel map either.

 

I had the same prob when I put my JRSC on, found out it was a leak in the TB gasket so I replaced it and it was fine.

 

The car idles at like 900 now, and is pulling 15" of hg, which is fine. I don't think its a vacuum leak. Never know though. I have a feeling that it may be a bad 02 sensor. I'm not getting and CEL's, but according to hondata, its putting out some funky voltages.

 

first things first i'd get the car on a good tune before you try diagnosing problems. base maps are meant to be just that ... starting bases. get it tuned properly then see how its doing
