wass up if you can help me it will be awesome please read thru all of it .

still have problems with idle going really low almost dying coming from 2k or lower ,anything higher going in to neutral it dies
i have no noticeable leaks or none at all

my replace list.... tb shaft seals, new gaskets in tb and intake mani has a new plastic "heat spacer" , no leaks on bov .not venting. new intercooler core , replaced isc motor from a 94 dont remember what it read but i slapped it in the old one was dead, , it helped with idle but it is still jerky, at idle going from 750 to 780 down to 718 ,94 eprom ecu ,adjusted biss grounding it , tps at 10% with logger, fuel press is set with aeromotive afpr

my fuel trims are as followed low fuel trim goes from 100 to 86, mid trim is solid 103 ,high trim solid 90 //// -7 on the low and hi throtle at 1k on the safc
where should my hi throtle be set at 1k ?

should i block of my fiav ? with a plate or fully remove it ?there is cold weather here not sure witch way to go

is it normal for my low trim to move that much around?

i blocked the lower part of the tb, fiav and isc ,with a homemade plate of aluminum i made and sandwiched it in between,adjusted the switch on the tb , i did a boost leak test found 1, so i have no leaks at all right now i can rev up higher like 4k without stalling it if i go higher it dies .

is it normal to go down to 500rpm when going to neutral (rolling) then it picks itself back to the set 900rpm ?
what else can i check for stallin problem ?

can runs like a champ no knock set at 18psi
