Thanks for the info brad.    id love for you to check out this wreck...
but I'm about 3-4 hours west of Toronto.
So what I. did was block off the exhaust an the intake    put about 5 psi compressed air into the intake track an started soap testing everything ..
when I was about to give up I heard a hiss , so.  I see someone installed an aluminum ear block off plate.   that thing was singing...   offf that. pos came on went a. crude piece of 1/8 steel plate I quickly ground up.   a little silicone,  an fired it up. not up. to par but o2s are in the 600 area. an the Wideband 14ish,


thanks again. Steve an Brad
Dave

what could be. the cause of low o2 readings at idle. like in the 100.  range?   new. sensor
an the Wideband to read 17.9. then shut off?


new motor roller cam roller lifters.   tt5.7 chip.  50 lb injs   stock mass meter

ok  i finally  drove my car  tonight...
so far  it  stalled  twice  once while off throttle cruising   coming to a stop,   an the second time  it started to run rough  then just shutdown?  no codes  on scanmaster
ok  now figure i better get close to home  so on the way  home i  step  into it an it  almost stalls,  hmmm


ok home in driveway  rev it up a bit an its like theres a   flat spot in the throttle if that makes sense?  starts to rev then nothing almost like  when you have a   4 bbl carb  an  the secondaries open too soon...


the only thing   ive changed  is the 4inch maf pipe  the translator an the 3.5 maf meter ..
ideas  lets  have em boys....    before the snow comes lol
