Blinking CEL
 

If I cant figure this out tonight, I will get the thing at autozone to tell me exactly whats up. I went to go start my car up today. The day before I was adjusting my throttle cable to get a better idle, I drove it around after and everything was fine. I let the car sit for the night and go to start it up and it sounds a little off with alittle sputter. And now I get a CEL. I go to check the CEL using service connector, and the CEL flashes once and then goes solid. I know its not a CEL #1 cause it never repeated. Also when I start my car the CEL just blinks. Did anyone have these symptoms, thanks.

Ok fast forward a few hours I got the autzone thing.
These are the codes that appeared in order.
P0302 No. 2 Cylinder Misfire
P304 No. 4 Cylinder Misfire
P1300 Random Misfire
P1399 Pending

My btm is set to 0

Re: Solid CEL
 

Im trying to reset the ecu and advance timing to .75 or 1.0 and see if that does the trick

Re: Solid CEL
 

It def started better, and the CEL went out for a few seconds but then came back on. It seems if I play around with the btm and the afc I will get it to not misfire.

My only problem is at this point I have paid $1500 at my local tuner to have them make the car reliable.
They did a hg replacement, waterpump, and installed headstuds, few other things, and tuned my car.

The tune fucked up in about 2 weeks ago and now the tune is fucked again. I dont understand this. The tuner has to be doing something wrong. I know the btm should not be set to 0. There would be no point in running it. I sent the admin of Turbod16 a message. Heres it is to HMT.

Please help me. PLEASE. My current tuner is AFC illiterate. My car is getting CEL for misfure cycl 2 and 4 and random mis fire CEL. Its cause of my BTM. The tuner set it to 0.

Heres my setup. 97 Civic DX Hatchback - D16y7
- Garrett AiResearch T3 48/60 Turbo
- 450cc DSM Injectors
- 1st Gen DSM BOV
- 5" JRC Intercooler
- SAFC2
- MSD Vortech BTM
- PVC Charge Pipe
- ARP head studs
- Castrol Quart Catch Can

Heres my afc settings:

I have an afr of around 10-11. I know I can do much better than that. I am considering buying a wideband and tuning the car myself. IF YOU ANSWER ME AND HELP ME PLEASE.

Thanks.

This is the last email from my tuner. BTW he put in new spark plugs when he tuned the car. He said mine werent right.

you may just have fouled plugs . Try some new plugs . but they have to be the 7 heat range plug ngk stock number 1283 . Gap to about .020 also you may have a issue with the plug wires . not sure but running the car with the afc is not as reliable as using a hondata system . But for the most part usally works fine. The btm is not really needed at the boost levels you are at thts why it is set to 0 . but it still works to up the spark as well.

Re: Solid CEL
 

lol theres your probelm get rid of the hack and get a chipped ecu from xenocron or buy an EMS!

Re: Solid CEL
 

Wrong! Next please. Dude I have what I have. My car hasnt even seen the strip once. WTF! I atleast want to run it a little first before I get an EMS. But I plan to acutally go OBD1 and run crome in the near future.

Re: Solid CEL
 

lol, a gap tp .020? i would def start the gap around 30-32 and see how that does. might want to take your dizzy cap off and check the rotor. by lookign at your afc settings it doesn't look very tuned, i know its been awhile since i messed with one but when i tuned mine the numbers were so orginized as yours.

Re: Solid CEL
 

This is very discouraging! I paid intense amounts of money to have my car pro tuned. When in reality I could of spend half the money bought a wideband and done it myself.

Re: Solid CEL
 

Yeah you pretty much got assraped! try putting in new plugs! gap them somewhere between .028-.032 .020 seems waaaay to tight, although it prolly wouldnt cause the misfire.

Throw that afc in the garbage they are ----.

Re: Solid CEL
 

Whos got a OBD1 setup Ill pay good money for a good one.

Re: Solid CEL
 

i love coke

Re: Solid CEL
 

Check EVERYTHING spark related...

Plugs, wires, cap rotor...replace what you need to.

Re: Solid CEL
 

Plugs were replaced by the tuner of his choice, havent even been in there for a month. Wires are brand new also. Blue NGK's. Im almost positive its with the tune. Im fed up with the afc. Im going with crome.

Re: Solid CEL
 

i couldent get a gay afc to run one 0 obd2 cars.. get od1 and loose the piggy back ---- bro it will make things much more simpler leave the afc and crap for cars taht a EMS costs over 1500 dollars for obd1 and crome is not far from reach xeno got your back..

Re: Solid CEL
 

its misfiring and you havent even checked the plugs yet?! It doesnt matter if they are 2 days old or 10 years old thats the first thing to look at, at the very least if they are dark just take a SS wire brush and clean them up real good. I have a whole box of bkr7's laying around and change them out almolst every oil change, cheap insurance.

Re: Solid CEL
 

They dont seem extremly oil fouled just alittle dark and some are wet. I cleaned all of them, I reset the ecu again. Im gunna try to start it up again.

What is the possibility of a bad ringland or valve seal? Not a month ago, I had a compression test of 180psi accross all cylinders.

Re: Solid CEL
 

Car starts up good with no CEL. Then starts to sputter and the CEL starts to blink again.

Re: Blinking CEL
 

if you take the afc off how dose it run?

Re: Blinking CEL
 

Funny. Im gunna order an ECU off xencron

Re: Blinking CEL
 

can you get your hands on a compression tester to check again? and get a spark tester too. (if you dont know how to do the bootleg way)

Re: Blinking CEL
 

Ok, I've been reading this for a couple days now and I figured I'd throw in my 2 cents.

Flashing CEL means catalyst damaging misfire. first STOP DRIVING THE CAR. second DON'T RUN THE CAR AT ALL IF YOU DON'T HAVE TO.

Now...

Disable fuel so the car will not start. pull your plugs. Get new plugs and gap them to 30ish. Put the plugs back in the end of the wires and put them to ground. Check to see if you are getting spark while cranking. My bet is you won't be getting any from 2 and 4. Next if you get spark, put them back in, enable fuel and run it to see if it was just a gap issue. If you don't have spark from 2 or 4 (or any for that matter) pull the cap and look at the inside of the cap and rotor. There should be NO (ZIP, ZERO, ZILCH, NADA) corrosion inside the cap or rotor, there also should be no oil, moisture, buildup of any kind. if there is REPLACE THEM!

you have already stated that 2 plugs are wet (gas fouled). While this may be caused by the AFC dumping too much fuel, realistically it is due to the plugs not firing and gas just building up inside the cylinder/on the plug.

You need to focus on ignition first in this situation, worry about fueling if ignition checks out.

PM me if you have any questions.

Re: Blinking CEL
 

You can't just order an ECU. OBDI would require a conversion harness and a 2 WIRE IAC. You need to do some research.

Re: Blinking CEL
 

I know this.

Re: Blinking CEL
 

do you have any extra O2 sensor lying around? When i had my hack it fouled out my O2 sensor an caused a rediculous misfire, swapped out the o2, gapped my plugs down and it was good till i was able to get crome

Re: Blinking CEL
 

Cant I just clean the o2 sensors. I dnt have any lying around. The o2 sensor closer to the turbo is fouled with spark plug foulers.

Re: Blinking CEL
 

Ok I think I got it. After I ordered the ecu from xenocron and the fuel pump and the new IM, I realised almost all of my resistors had broken off the wires. My tuner attached them to the fuel rail, it was just waiting for the vibrations to break it. That might of been the reason for the misfires. Blahhh. :6

Re: Blinking CEL
 

how it run without the hack??

Re: Blinking CEL
 

havent finished the build yet.

Re: Blinking CEL
 

so how is you car running'?

Re: Blinking CEL
 

AFC ftl, Crome ftl, Hondata S100 ftw! Now its my internally gated Ford T3 starting to ---- the bed. I need tires, turbo, and external wastegate.

Re: Blinking CEL
 

run a resistor box i ran inlines 1 snaped and while i was racing and it cracked my ching chong manifold

Re: Blinking CEL
 

that reminds me, i was running individual resitors, and those a few of those broke causing a misfire!

Re: Blinking CEL
 

u will not have more problems . good choice.
