car runs great for first little while... then it begins to buck... ran fine tonight, but had 1600+f egt's, is that bad? safc settings 0 across the board

when the days are warm, the car seems to run like shit

oldman, yes a boost leak check has been performed.
everyone else, no, the ssqv is not recirculated, but that can't be the problem i don't think


any ideas?

quick guess, but with EGT's over 1600+ and the car running bad on hot days, I would assume a lean condition.

oddrob, thanks for the reply.. I thought lean, also.. so i added fuel, and the problem got worse.. so i figured rich, so i removed fuel, and there was not a big change.. o2's look good for the most part

Have you done a boot leak test? In all seriousness, the combination of venting and fpr overrun on the Commeand Flo is probably not doing you any good.
