This is a continuation of this thread, since I bought the car now: https://honda-tech.com/zerothread?id=1856551

The car has been bogging when I apply more gas, but its kinda random. It didn't do it when I bought the car, then 2 days later, it started doing it when I was at WOT, it felt like it wasn't getting fuel. The previous owner replaced the fuel pump, with out prevail, so I now I replaced the fuel filter (as suggested by someone else). I haven't had a chance to see if it helped or not, because like I said, its totally random when it does it, I can't get it to do it when I want to. It could be a beautiful day, car driving excellently, and all of a sudden, I go to pass someone on the expressway, or give it a little gas when the speed limit increases, and the more I give it gas, the more it bogs down.

Someone suggested checking the MAP/TPS sensor plugs, I swapped them, and it was worse, so I don't think its that.

Also, the car idles very high, like 1500rpm weather its hot or cold.

Last of all, when I was doing the fuel filter I found 2 plugs that weren't plugged in, does anyone know what they are? And could it have anything to do with my problems? Here are the pics. The first one looks like it comes from the firewall. And the second comes from the harness that goes into the distributor.

Thanks in advanced, hopefully someone can help!

Okay this sounds like you got a big problem. First thing is first.
Any CELs?

Powered By Garrett

No CELs <u>BUT</u> the CEL light doesnt seem to work. It does not light at KOEO like its supposed to, it does not light when the diagnostic plug is jumped. And its not the bulb, I took the cluster out and checked the bulb, it wasn't removed, broken, or burnt out. And I replaced it with a known good just to be sure (the brake light) and it still doesn't work. What else could be causing the CEL to not work?

Try to go to a local auto parts store and pull codes with a reader.

They only do OBD2 cars

This is so freaking wierd. If anything that plug coming out of the firewall looks like a EVAP connection.

Well i'd say theres a 99% chance with the car running like this that its throwing a CEL. HOWWW can I fix my ******* light? Is there another way that someone could have made it not work since they didn't remove the bulb?

Powered By Garrett

So I tried something else. I swapped a virgin p05 in (cx ecu) and still no CEL, but when I jump the CEL port, the SRS light flashes continuously, does this mean anything?

dickowskiflowers

well... just a question, but have you checked your fuel pressure? My friends car was bogging down hardcore, and then he got a fuel pressure regulator and that fixed the problem quick...but his car was also very strange, with lots of things wrong with it, so it could have just been a miracle

Powered By Garrett

No I dont have a way to check the fuel pressure, kinda broke right now, just want to get the car running normal for my wife before I leave for Iraq on friday

Also, I read the ECU thread, and it says the plug is supposed to be grey, with a black and red wires coming out of it. Mine is blue, with one brown, one black wire coming out of it, and it doesn't seem to do anything (exept make the SRS light flash) am I missing something? Could this be why my CEL doesnt light up ever?

Heres my plug:

So I got to thinking, maybe someone fucked with the wiring, and thats why the SRS light blinks when the plug is jumped. So with it continuously flashing, that would mean o2 sensor. So I looked at the 02 sensor, and the wiring was cut before the plug, and it doesn't look right. Can anyone help? Heres the headache:

<u>Coming from the main harness:</u>
Orange/Blue
Green/White
Yellow/Black
White
White/Blue
Black
Orange

<u>And the female plug (that goes from harness into o2) has these wires:</u>
Grey
Black
White
White

Since you cant see too well in the pic, the wiring goes like this (I used pink for white):

you are using the correct harness for the CEL jumper.

if there is some wiring issues, it could be that your srs light is now your CEL.

jump the connector and try reading the srs light blinks for a code.

Powered By Garrett

Figured it out, sorta. I guess the one of the ******* who owned this car before me cut the wire harness for the CEL light. I fixed it. Its throwing code 41 (Primary Oxygen Sensor - Heater) what does that mean, and does it have anything do do with my problem?

Could it have something to do with the way the o2 sensor is wired up?

92ehatch

it can and most likely is the cause of your problem.

it could be the wiring as well. try rewiring it and soldering the connectoins, then use shrink wrap on them.

edit:

if your SRS light really is your CEL now, then if you are throwing a code your SRS light would be on all the time...is it?

No man its not, I got the CEL working, and its the one throwing the code.

And what the hell is my o2 sensor wiring supposed to look like? I got 7 wires coming from the harness, but only 4 on the o2 sensor.

92ehatch

what motor? i only know little bits about d series and nothing else

d16z6 in a vx chassis

i think i got it figured out, after lots of searching (on ht and google) the asshat had the wiring backwards on the o2 sensor, i redid it, and now now it doesnt trigger a cel on the p05, the p28 although, still throws the cel, but i think it just has to reset. i unplugged the battery and we'll see in the morning. but i took it for a test run and it feels GREAT with all the new parts (fuel filter, wires, plugs, correctly wired o2 sensor).

so i think i got it, thanks for all your help guys!

also, is there any way, when i chip the p28, to make the shift light work? thanks

Boostedb20EH2

My old integra did this.
Not fun,it only did it occasionally but i could never figure out what it was.

have you wired in vtec? if not thats why the p28 throws a code probably. as far as a shift light, i dunno. i know some people can make the CEL pop on for a shift light.

glad you got it fixed tho. mabey my o2 sensor is why my car bogs every now and then

As far as I know VTEC is wired. All the wiring looks like its there at the main plug under the hood, and again at the dizzy, and at the ecu, so unless something is cut inbetween there. And it "sounds" like vtec engages on the p28 whereas it doesnt, on the p05 (of course, since the cx is non-vtec)

Powered By Garrett

Okay. It sat overnight with the battery unplugged, and its still throwing the CEL on the p28, but not on the p05. WTF?! Anyone?
