from what i understand 02's mean nothing unless your at WOT

Youre 02 sensor is probably contaminated. Try changing it the non heated 02s from bosch I think are $20 or mabye a little less. Its been a few months since I replaced mine. By the way at WOT the cumputer does not take in 02 info. It resorts to open loop mode and goes to a preset A/F ratio

ah but im looking to address it at idle first. idle count is at 700 rpm count reads 16 - 20

You got 11 degrees of retard while only flowing 62 grams of air through the MAF? The O2s look a wee bit lean, but the low MAF is throwing me off. BTW, with 4650 rpms and only going 32 does this mean you were under WOT? If so it seems a MAF problem exists.

Those number don't jive at all.

tps is 1.63, mph 32, rpm 4650, maf 62. ????

There's virtually no way these are from a single frame unless the ECM is garbage. Was this a steady cruise or WOT blast?

 

[eddiedellz]

wot blast im gana record another spreadsheat today and do a cruze , wot and idle.. see if i can get that spreadheet up.
