Hey,

Ive searched everywhere on the forums to fix this issue im having...For some reason my car when the headlights are turned off will drop idle to around 750 sometimes close to 700 and the car feels like its going to stall.

When the headlights are on the car runs fine. If the car is warmed up and you go to start it, it will start then the idles will drop below 600 almost stalling and going back up to around 750 to 800...Also when i come to a stop at a light with my headlights off it shakes and almost stalls.

What ive done:

Already replaced the map sensor with the MAP fix, regapped my old plugs, and replaced the plugs with oem platinums...

I am not sure of what else to do so I am in need of some help i want to get my S back to a healthy condition. Any input would be greatly appreciated.

Stock ecu? checked ur Idle air control valve?

 

For AP1s the idle speed is 800RPM ±50RPM.
This is per the Honda Proformance technical manual. Not sure about the AP2.

Check battery contacts for corrosion. Is your CEL on? Last time mine idled like that I had 100psi compression on cylinder 3

 

stock ecu...ill look up how to check my idle control valve..


also i did look up online my idle should be around 800 +- 50 but the car shakes a lot at 750...

ill check my battery contact but they were pretty clean when i did a ecu reset..no cel light.

MODS:

AEM V2
PLM header
test pipe
HKS single 75mm

but its been doing this for a while.

 

Wierd that you didnt get a CEL. Is your CEL light working?
How many miles on the plugs?

I'd run a compression test.

 

i think the CEL is working idk lol...plugs are brand new now...ill try a compression test after i clean my IAC valve just looked up the process.

 

try cleaning your iac valve. im aem ems, i idle at 1k lol. its annoying when the idle dips, so i set mine up at 1k, no more dip stall stuff.

 

^^ If I had an EMS I'd set it to idle at 5800RPM, F1 style

 

Did you follow the proper re-learning method?

 

whats the proper relearning method....ive followed what was on this site....after i reset ecu, i start the car let it idle for about 5 minutes and then take it out for a drive...is that not right.
