For some reason i'm having idling issues with my swap. H22 into EK. Obd-I motor. With gas runs like it should but at idle it "purges". Any suggestions? I was thinking maybe a vacuum problem. If so do i need to have all the different check valves and what not?

 

What do you mean by "purge".. can you describe the issue more clearly?

Here's a common issue with all honda engines:

look at step 8.

this valve works itself loose (unscrews itself) over time. A lot of the time you just need to screw the valve back in, put everything back together and you're good to go. The thread is for a gsr motor but this valve is similar amoung all honda engines that use them.

There are a lot of other threads regarding the "FITV" if you want to search.

 

Mine did that and it was IACV. Idle surge, eh?

 

i guess it can be described as a surge. revs high then low, high then low, high then low. Kinda like if you went on and off the gas.

PwRLiMeH22 - how'd you fix it? you just changed the IACV?

 

Anybody else?

 

yeah thats what id start with. sounds like the problem. my friends car is doin that right now i told him to change his.

 

Is your EGR hooked up, if not you need to make a block off plate.

 

no, egr is not hooked up. can anybody gimmea "how to" on a block off plate. for some reason i sound like a damn noob with this crap. also keep in mind that it's only doing this when it's cold. once it heats up it's fine. could it be the coolant temp sensor?

 

ok, maybe not?
