My car runs good but idles very poorly. Here are some scan test data i took this morning. Anything seem not right?

MAP 15-16 hg
Baro 25.41 hg
MAF 10.4
fuel integrator 123
blm 123
right blm 122-124
inj pulse 4.00
right inj pulse 4.00
iac 95
O2's are normal
this is all at idle in gear

thanks!

 

After reading Fred's page it seems my iac is maxed out at idle and the maf is a little on the high side. What does this mean for me? Why would the iac be maxed out? There has got to be something causeing these readings.

 

IAC is not max'd out.... it can go higher than that. But you don't want it that high.

We all need to be careful here, looking at this data, because you are at such a high altitude. I'm not sure how that affects all of the readings, since I never see data from ~5,000-feet.

The MAF number looks a little high, but not anything I haven't seen before. Does your MAF have the screen removed? The pulse widths look a little high too. I would expect something closer to 2.0mSec.

But, the air and fuel seem to be matched up pretty well, because the long term fuel corrections are even on both sides, and only pulling about 4% fuel... well within normal tolerance.

Seems like a bit of a contradiction.... MAF reading a little high, and IAC a little high.

Have you had the PCM programmed for the HOT cam?

 

Yes i have had the pcm reprogrammed and it ran excellent with the tune until recently. The maf is stock and untouched. When i unplugged it the car smoothed out a little at idle but i didn't try to drive it.

Another thing, it smells real bad at idle and will make your eyes water. I guess its running real rich.

Thanks for the help!
