[RESOLVED] Erratic Front o2 volts? DSMlink log attached [Resolved]

[ApexVIII]

look at my front o2 volts.

my car idles really lean after pulling the head/timing belt and installing 264/272 cams


any ideas? i am doing a boost leak right now, and the compressions is 180 for all 4 cyl

Looks like normal operation to me.

Read where it describes closed loop.

Perhaps you have a leak before the wbo2.

Your AirFlowPerRev seems a bit high, but nothing alarming. It does seem to be running lean and your vacuum seems to be a bit higher than normal.

But the o2 looks fine.

ok, i just cant figure out why it is running so lean at idle, befor the cams it was cycling around 14.7

there is no boost leaks, there might be a leak at the DP, ill check that right now

i think i found out what was wrong...

when my friend put on the DP, one of the studs was mesed up, so when he tighend one side it went down all the way,

when he did the other one he tighten it almost all the way then it stopped and he thought it was done, but i had a exhaust leak there so im hoping that is it

im gunna go look for some replacement bolts for it

thanks for the input!!

Fix that and I guarantee your wideband readings will be closer to normal.

I'll also suggest that you switch over to the new V3 application. We maintained backwards compatibility with all our previous chips dating back some 7+ years. So there's really no reason not too. You'll get a MUCH cleaner interface and much easier navigation features.
