hey guys, i am trying to figure out an air leak or something cause im radomly having idle bouncing. i am feeling its the intake manifold and the throttle body i have from skunk2 but i could be wrong.

does anyone have these combo?

do you have random idle bouncing?
i get it after i drive and its warmed up but once in a while at a stop light it will not bounce. the idle is good. then it will do it at a different stop.

 

no problems here you might just have a vacum leak

 

yeah iv never heard this check all ur hoses

 

only problem i have had with my skunk2 intake manifold is firewall clearance, or lack there of... my iacv is resting against my firewall blanket thing. thankfully i have prothane inserts so my motor doesn't really move at all...

 

check the vacuum hose to ur pcv valve, jus read a thread called idling issues, he replaced a bunch of sensors and it was his oil catch can(pcv valve) hose

 

thats already replaced. i am checking hoses. there arent too many hoses. they seem tight and fitted.

what about the temp sensor. since the hole didnt fit perfectly its kinda kinked. i was wondering if i shouldnt have used my old 91 oem sensor.
should i be using a different year or something?

also when i took out the throttle body air adjuster the idle bounced the same as with the round screw was tightly in.

 

thats strange i have lots of clearance and i got a b16

 

SOHC S2 Intake manifolds have like a finger clearance to the firewall.

 

I got the same problem with mine..no clearance AT ALL!! 91 dx
