idle adjustment

[NtAcivG94]

i know there must be a way to adjust the idle for my car...but i am not exactly sure what to do...my idle seems unusually weak and by weak i mean after it has been running for a bit and is at normal operating temperatures it will idle at about 200rpm...id expect it to be atleast around 800-1000rpm...any suggestions:neutral:

ok nate this is what ya do..... sell ur turbo stuff.... blow up the SOHC and be a man and go DOHC!!!!!!!! eheh jk... you could mess with th idle screw on the Throttle body....

[NtAcivG94]

someone on HT said it was a timing issue...would a new belt fix that?:hoppingmad:

[Mr.EM1]

You can tighten your throttle cable. http://www.clubsi.com/howto_throttle.shtml

i'm having the same issue to, i try the idling screw and other methods and yet it hasnt solve the 200rpm idle. i'm going try the link in the last post.

i asked some1 on H-T if a vacuum leak somewhere could be casuing it and he said yes. so later on today hopefully i will look for a leak and i will also idle positioning sensor and the idle controller sensor



bleedhondos...let me know how that works out for u

Nate the proper prcedure to adjust your idle goes as so

IDLE ADJUSTMENT

First start the engine hold the engine at 3000 RPM with no loads until the fan comes on then let it idle.

Disconnect the IACV Idle air control valve.

turn off the engine

start the engine with the throttle slightly depressed and stablize the idle at 1000 RPM then slowly release the throttle until the car Idles.

Check Idle with no loads on no radio ac headlights. Nothing at all on.

Idle should be 420 plus or minus 50 RPM if not adjust the Idle screw to make sure its at this RPM

turn off the engine reconnect the IACV Plug and remove the back up fuse from the under hood fuse box for 10 seconds

Restart and idle the engine for 10 min idle should be 650 plus or minus 50 RPM

Idle the engine for 1 min with the headlights on idle should be 700 plus or minus 50

turn off the headlights and idle the engine with the heater fan on high and the AC on for 1 min idle should be 810 plus or minus 50

IF you dont have a good idle after this check your ignition timing if its off get it to spec then restart this procedure

My 93 EJ1 used to idle at about 300 RPM warm... I never really had a problem with it...

[boosteddx]

i just got down wiht my swap...im suffereing idling problems right now too...but me i know its timing..no codes or nothin so it was a perfect straightthrough swap and wiring. dont know u could have skipped ur timing

I try that awhile back and my engine still idle below what is suggested. I should check my ignition timing and get it back to spec. Stupid question...how do i go about doing the ignition timining?

[NtAcivG94]

well my idle is now jumping from 1000-1200rpms sometimes...the IACV must be messed up?

[Volume 8]

that's really weird, i'm having the same problem, i keep getting a code 14 here and there too, but the mil hasn't come back on so i have my fingers crossed.

[NtAcivG94]

im not throwing any codes or anything....the idle is just acting up for me

[SittinTooLow]

I got a '95 Coupe with the D16Y8 SOHC VTEC swap. I had the same problem when I finished the swap. My problem was idling at like 200-300 RPM.. took it to a local shop, said it was a faulty Throttle body gasket. Bought a new gasket, fixed it. Now the motor idles at 600 RPM always. Thats just a thought...
