as the title says guys i got a b18a1 and it got some problems..and i could use some help please..

it blew a head gasket..stopped drivin it ammediately..bought a whole decent head..cams and everything decent,better then the old head..replaced all that so on and so on..get it all back together and runs fine but the idle is horrible..

-high idle 1000-1700 (sounds like it has serious cams) but surgin at the same time..

no codes are present..i have the right ecu..timing and everything is good..
cleaned the iacv and fitv..changed the map..changed the pcv..vaccum lines all connected..now im tryin to is fix this problem..what do i do?

did you try adjusting the idle screw on the TB?

also, be sure the IM/TB/IACV/FITV are all tightened down properly.

dougy_fresh

yea i took all that apart and cleaned all that and everything is tight..

skunk2racing97

did you pull the throttle plate out?

dougy_fresh

yea and adjusted the white screw thing almost all the way in..like i was told..

skunk2racing97

the white screw thing in the FITV? lots of people do, and the only prob you will get from that, if anything, is that it will idle low, which is not your prob.

as for the TB, is there any chance the allen key screw (with the 7mm nut) that holds the throttle pulley is keeping the plate from shutting properly?

also, did you try to lower to idle using procedure? (removing the IACV plug and resetting the ECU)

dougy_fresh

i believe the 7mm nut is fine..what does this nut do?
and yes i tried lowering the idle and i removed all sensors and pluged them all back correctly and tight..and i reset the ecu 20 times! ha..i just dont know...

skunk2racing97

there is a very small allen keyed set screw that is held in place with a 7mm nut that keeps the throttle plate from closing too far and getting stuck.

dougy_fresh

still stumped..bump!

sounds like typical ls....check for vaccum leaks after map and tps sensor...intake mani and also where the pcv hose goes to the box under manifold make sure its in it good....will cause ur probs....lmk
