ok i have a b16 block with a gsr head and itr tranny running off a jdm p30. butterflies have been removed from the manifold. motor ran fine when i put it in...after awhile it developed this bogging idle when it warms up. it comes and goes. car idles fine till it warms up then sometimes as its idling at 700 rpm it putts and boggs alittle to 600 or 650 but its not the speed thats concerning me ... its the putt noise it make just was it boggs. ive also noticed there seems to be a very slight sputter in the idle when its not doing this. ive tried a couple good dizzys and a different ecu but i still have the same problem....please any help

 

anyone have any ideas?

no idea.....but someone might chime in, free bump to you....it might be dirty injectors but i dont nkow....

 

Try reconnecting the butterfly. I doubt that it the problem. IACV maybe?

 

its not the butterflies bc i had no problem without them for quite a while....ive tried cleaning the iacv...i may just go ahead and replace it

 

i cleaned my map sensor and iacv worked like a charm,if it doesnt work at least itll only take a minute or two to do.

 

Try to clean the screen on the fitv. if the problem still occurs make sure your coolant system has no air in it.

any CELs? if not then clean iacv and map. I'm sure something along those sensors are making the bogging idle. I had an OBD2 LS in my 93 hatch was doing the same thing, I had to reconnect all sensors on the mani and replace broken connectors worked like a charm my bogging idle was no more. Hope this helps.

no cels...i have no damaged plugs or anything like that....ill try swapping the map out for a known good one
