Yup...

Checked codes today...

P1101 Intake Air Flow System Performance ECM, PCM..What does this mean?
P0330 Random misfire

Any thoughts? Never threw p1101 till after your tune...?

 

thats an odd one actually. i have thrown a lot of codes on my car, but never that one. have aj clear the codes, and log the car.

 

ok well either way...Not sure what to totally say here. I am throwin more codes...

P0171- upper bank sensor to lean
p0300- Random Misfire

Threw these with in 5 min of driving...Seems i am throwing more after then i did to start with the tune. Tonight i am hitting 12-pounds instead of 15-18 like i should be.

1st pull-15-18 pounds
2nd pull-14-16 pounds
3rd pull-Hits 15 for 2 secs and holds twelve.

Wasnt this tune spose to help with that? It has to be heat issues....Is there nothing with in the tuning that can be done? I thought the tune was spose to take this away...?

 

We will mess with it tomorrow, ill call you when I get out of class.

Interesting night tonight, heh? lol

 

Yeah get some logs and post them up so we can see them. I would like to take a look at them too...

 

you mentioned throwing 300 BEFORE i touched the car. 171 is a common problem on cobalts. i did not touch the boost side of it.

you keep throwing the p0300 for a reason. it doesn't throw itself for the hell of it. a tune will not fix mechanical problems.

im comparing the file right now to what i did to it, and what i pulled out of the car.

what i did to it. changed the PE. changed where it hits pe at. DTC's for the catless downpipe you have on it. some adders put back in and/or changed. fans changed. and mas air tweaked.

care to keep pointing the finger at me?

 

No no my freind i am not mad at you by anymeans. Sorry if i seemed like i was. I wasnt trying to attack you or pointing fingers.And ya i knew i threw the 300 code before but i thought you said the MAF change would help with that? But alls i am saying is i am just having the issue and you had tuned and it made the car quicker yes but only when boost holds. any thoughts?

 

Get the logs, make sure everything looks kosher as far as logs are concerned. If the logs look good then you have a pressure leak somewhere. Could be a hose, the bypass, a gasket, etc. The problem happened after you swapped the pulley and injectors and took off the TB, so I would focus around those areas to try and find the leak (if it is a leak that is).

 

the maf tweak has nothing to do with the p0300. bad plug, bad injector, bad coil pack, and the worst of it all. cylinder going dead. the 171 is a maf code. it's getting cold. you have 60's. it's going to be a common problem without a lot of baby sitting with hpt to mess with the settings every day. welcome to the wonderful world of a temperamental lsj

 

Wow well i really hope its not a dead cyclinder..it only has 29k on it. That would be messed up if it did thow. When i bought the car at 25k it appered to never been abused and still had the stock tires on it. Which apperently is a big deal cause they dont last long. Had never been in for warrenty work. The only i had done to it was the clutch when out from the last driver which i got for free.

 

i would be extremely safe with it. it could be as simple as a bad plug. also, check your gaskets for leaks as well.

 

Welp the whole setup is just kinda messed up. It did the slight misfire sound even when i 1st bought it but never threw a code about. i am about to just say **** it, Put it back to stock and just drive it

 

put everything back to stock and take it in for warranty

 

Cant. i traded my stock DP for the vibrant one with no cat. SO....no matter what unless its super major i cant...removing the cat is a big no no LOL

 

I have 3 WOT logs, and each one, he is loosing boost more.

 

Hi welcome to the world of the poopie LSJ, Hey if you need a Downpipe you can use my stocker....Well no blown motor for me, my car has a bad fuel filter, needs a new injector harness, new header gasket, coolant pump, new spark plugs, new MAF and new O2 sensor, the tech said sometimes it doesnt even run on 4 cylinders haha!!! Wooo hooo i hate this car now, im waiting for the new Lancer Ralliart, Smart fortwo Turbo, or Hyundai Genisis coupe turbo to come out and the saturn is gone, i got 2k in the bank for the downpayment and i just started an insane job so im banking. Im moving into a house with my buddy in chesterfield in the next couple months as well after his house sells in kirkwood. Glad to see everyone liked their tunes though!

 

Was a known good wideband used during this "tuning" session? If not, thats the first "no- no"... Second, a P0171 is not a "MAF code". It is a lean code. Also, was the VE table tuned? IF the MAF is failing this could pose to be another problem. Also, if in fact there is a mechanical problem, this should be the 1st priority. Never attempt to tune around a problem...

 

hey if you really had to i could let you borrow my dp lol if its serious enough

just realized some one already stated that.... reading > me

 

the boost issue is a mechanical one. aj. you have the file to look at as far as boost goes. it's not the tune doing it. the maf should not be jagged like that. the sad thing is. a dealer will not pick this up on the tech 2 either. now it's down to trial and error

 

So, what do you suggest? I guess check all possible culprits for a boos leak? Justin has been checking the lines and gaskets, we need to pull the blower off and check the blower to lower IM gasket.

 

justin. go to the dealership and get the actual tb gasket for these cars. make sure when you put the gasket on, that ALL of the silicon you put on is gone. it MUST be spotless when you put it back together.

 

Yeah I have to agree with Brian, there is definately some kind of leak or mechanical problem. The boost and MAF are freaking erratic as hell. Have you looked at the intake and filter to make sure there aren't any problems there?

As a side note - no KR and the IAT2 looks pretty good.

 

These have yet to be answered???

 

first off "master tuner" what causes the p0171 and p0172 to trigger.

second off. since when is tuning without a wideband a no no? the last two cars i did without a wideband that were curious about it were dead nuts on exactly what i wanted them at. m-dub's car and ralliartist's car. go ask them.

before you try and jump my ****, his problem is mechanical. not the tune.

 

When you mean gasket are you refering to the SC gasket? or which one?

And ya i will take a look at the MAF. The only thin have done is the air box mod with a spectra filter(i know its AUTOZONE **** but its still a filter
