i just rebuilt my motor jlp stage 3 cams, pistons rods i put 1000 miles on the motors feels stong. im having an issue with my air fuel on low load it can go all the lean on a aem wideband or rich. when it goes lean all the way you just give it a little gas and it goes back to normal 15.5 or so. issue is mainly seen at very little gas or idle. and sometimes it will go rick all the way again a little gas and good. now the question is has anyone seen this before?? change plugs to tr6 gapped at .32 new fuel filter, tps adjusted to .98 on key open not started. any other ideas or what to try??

Either a vacuum leak or tune issue most likely. WHo did your tuning?
Check your fuel pressure.
i guess i could see it being a vacuum leak.. the tune is a diablo tune for 13-14 pounds and i have richen it out on wot at both points. i need to get the fuel pumps and get it dyno tuned. does anyone know any good shop in florida that works with diablo. thanks for the input.
