im stuck on this. working on a tune for a friends car. car runs great, idles peachy. randomly throws this code. it can't be felt or anything else. it has done this since the 60lb install and map change.

im lost on it. help!


set the minpw lower and see what happens? the rest of the injector tables are pretty much the standard tables for the 60's. one thing i have noticed is, there is variations in everyones map. be it dwell time, or something little here and there.


i do know, on this particular map there is changes in the dwell time as well. but i don't think it would actually cause it to pop the code, i think it's in the injector side of things

 

i'm guessing too rich and you're washing a plug or two, or one of the injectors is bad and not giving enough fuel to a cylinder so it's not firing at all. the code is random misfire. pull the plugs and let us kno what u see.

 

I use to toss that. Then I changed pistons and it left

 

i was leaning more towards bad plug, or injector. no one else has gotten this code. wierd wild stuff.

we really don't have control over the idle a/f or airflow itself. so yea. it's more or less up in the air. guess i need to stick a wideband on it and see whats going on. at wide open it's peachy

 

I got this code a week after installing my 60# injectors and 2.7. It happened when I went hard on the gas to get into traffic on the interstate. This was in the winter time and I happened to not let the car warm up before getting on it.

 

**** you don't have a wbo2 on it??? um, yeah, might wanna get one of those..............

 

that should have read, stick one back on it. everything seemed fine before. the weather plays hell with cars here. getting it exact one day, will throw it off the next

 

since its my car lemme throw some more info in.

like he said. only at idle, and its not set very often. just when i idle for 5 or more minutes. say waiting in line at a drive thru or a long stop light usually happens in neutral, with my foot off the clutch, but has happened once with the clutch pressed in in gear. probably doesnt matter though. happens with the a/c on or off umm.. it drives fine, it idles fine, anything between idle and wide open is great. pretty sure its not plugs..the plugs are bkr7es or whatever..

...yeah thats it

 

i'm going to say it again. pull the plugs and look at them. yours is doing exactly what mine was when i was washing the cylinders out and 1+ of my plugs wasn't firing because the chamber was flooding. at WOT it was fine, but partial throttle and idle it wasn't. if you had a wbo2 on it the convo'd already be over cuz you're probably at 8 or 18:1.

 

part throttle is fine in the car. guess there is a couple ways of finding out.

most likely be taken care of this weekend

 

got the same code... whats wrong with it???????????

 

do you have 60's?

 

are you running colder plugs?

 

you may have checked this......but when you installed the 60's you didn't pinch an o-ring or something did you?? A vacuum leak would cause a misfire at idle....just something to look at. Good luck

 

got this code when my number 2 injector went bad,replaced it,no code,at least for this.LOL!!

 

what is this code?

 

missfire code.

figured it out. now i know how to trigger it and mess with peoples heads

 

what goes bad that causes this code?

 

the cause of my problem was in the fuel side of the map itself.

 

yea, i know my maf is dirty cause i accidentally touched it with my hands n dirt got in the box once when i removed it so i figured it could be that but also thought maybe the coil or plugs. im gonna check it all but i got 2 weeks to do so and get my bushing for the control arm on passenger side fixed along with that balljoint so i can go get my car inspected

 

Explain?

 

min pw, and short pulse limit. errors in these caused it.

 

Was that on my map? Also, short pulse limit cannot cause a problem really. That just tells the ECM when to look at the adder table. Min PW won't cause those either as long as your adder table is correct. If it was my map, then the adder was likely the cause, as I STILL have not gotten a perfect adder table together yet, although the one I am running now is really close.

 

nope, it was someone else's map. i already fixed the issues with my current map {which is peachy btw}

 

Sweet.
