misfire on all 4 cylinders?

st paul

 

oh hmm i may stop by tonight then does it take long to log or something?

 

to pull up a learning view only a minute or 2. Log takes a bit longer as to do a proper one you should do a 4th gear pull 2000rpm-redline

 

hmm ok i can prob drop by to check on that learning view

 

learning view after 7.5 miles

 

Anyone can do a boost leak test, nf?

 

Or have the tools

 

Just out of curiosity, what exactly does all of that tell you? And I'm assuming that one random -2.11 isn't supposed to be there.

 

I believe that is knock

 

the lower table is knock. The upper table is fueling.

 

Silly question...but did you fill up on a bad tank of gas? Have you filled up again since you started having trouble?

 

I let the car sit a week then drove it and that's when the cel came on have filled up and even used injector cleaner But could still be a bad gas um I am hearing a whistle sound now tho so as Jasonojordan said A post turbo boost leak causing a lot of fueling maybe not sure

 

so talked to my tuner and gave him a copy of my learning view and he said its pretty good but he wants to scale my maf at idle

 

You told him that learning view was at only 7 Miles right? For a learning view to be real accurate on your fuel adjustments you should have close to 100 miles on it. I realize you have issues that could prevent you from doing that many miles if the car is misfiring.

 

after 25 miles



Tried to pull his map but for some reason my ecuflash was on the rag and would not pull the map.

 

hey by any chance are you able to do like a log for my car? would probably have to check and send that to the tuner might be more informational to him not sure thanks

 

Lets start with Ill get the map pulled and we can send it to your tuner. I think I got my ecuflash sorted out now so it should work properly. Im a bit leary on wanting to do a pull to get a long with that big -10deg of knock...thats alot..like woah alot.

 

That does seem like a lot of knock but it is at low rpm and at less than 1g/rev of engine load so it might not be too bad.
Either way the tune seems like it needs tweaking but at least it wasn't knocking in boost at high rpm.
Disclaimer: I am not a tuner haha

 

fuel trims are acceptable. it can fluctuate.

as for the knock, i'd retorque your knock sensor to factory spec and placement.

 

ok thanks guys will be taking intercooler off and seeing where my boost leak is at anyways so will retorque the knock sensor at the same time. Nuke is nf able to go through my car and give it an inspection as im lost to what could be causing the misfire codes and my idle is rough so not sure on that hoping to pull the map and hoping my once my tuner scales the maf at idle itll help with the idling but still not sure on the misfires

 

Bump for any word if the problem has been resolved?

 

nope thinking of finally bringing the car to get it professional checked i mean im not losing power nor do i feel any loss of power so im stumped

 

so after a few months jsut driving the car the cel just up and disappeared hmm crosses fingers
