Well Ive been suffering the infamous surging idle issue (up and down from 1000-1500 rpm) Im running the jdm auto p08 ecu in my manual car idk if this matters. I replaced the IACV the Fast idle control valve and the pcv valve. Still does it. Ive checked for vaccum leaks cant seem to find any. It will surge for about 5 minutes straight just sitting there then will idle fine but if you hit the gas pedal it will start surging again. IDK what to do should I play with the throttle screw on the throttle body? oh yeah some times if i hold down the brakes hard it stops but not all the time
any help would be appreciated
Thanks
John

 

i did search there is just many variables when it comes to surging idle issues

 

auto ECU in 5spd causes that idle spike, trying to compensate. your option is to convert that ecu to 5spd or chip it to avoid it.

if you want quick fix for DIY guy, get a soldering iron, open the rear ECU cover and remove RP17. (tiny SOP resistor)

 

thanks bro I'll prob. do the quick fix. Just removing that cant be to bad....I know I asked you about chips before but I cant decide if I wanna boost this sohc or go dohc thannks a bunch

 

do i have to put a jumper wire in at rp 18? or is that not necessary? Just found an old thread

 

 

b4 work bump just gotta know if I have to jump rp 18 or just leave it be?

 

http://www.hondaswap.com/~pills/autotomanual.html that place tells you step by step how to do it good luck partner

Well I did exactly what you said just removed that one resistor and it runs mintttt!!!!!
Those suckers are small
Thanks ALOT

 

some pics of what I did..... thanks again for the help solved my head aches

before rp17


after removal of rp17

great, enjoy...indeed leave the rp18 there, the way it is. since you have no access to smaller resistor (as in resistance value) and size and it simply does nothing.

 

Is that just with the P08, cause I'm having that same problem with my 92 dx? Would that res. be the same on the dx ecu?

 

I dont think they are the same but Im not sure this was for my JDM p08 ecu

 

i was having the EXACT same problems. im running a jdm d15b with a auto ecu. i just took out rp17 also. my car sounds sooo much better!
eg6ajk- thanks for the info, youre a genius!
japspecjohn- thanks for the pictures! made it much easier!

 

no problem Welcome to H-T.... glad I helped
