i just added a cold air made with a k&n filter. On my first test drive i noticed that we started to bog out (really bad) at around the 4000 RPM range. I have the stage 2 from GM installed but I DO NOT have colder plugs yet could this be my problem i also do not have any codes reading.

 

Did you unplug the battery and reconnect it, we had the same issue on the ion. I disconnected the batery and reconnected it, and everything was fine there after.

 

Thanks I will give that a shot

ok so unplugging the battery didnt work and now i cant get past 4500rpm in all gears any suggestions

 

how long did you unplug the battery for..i heard about this once i think...leave it unpluged for like 10 15 secounds i thnk the guy said but i m not sure..it was a couple weeks ago...

 

it was unplug for 1/2 hour still not running good i am also getting a funny smell something i have never smelled before if i was running to rich or to lean would i get any codes.

 

when you put in your MAS did you touch it by any chance? Check the connection to the MAS. I just installed my Injen intake, and no problems what so ever.

 

would i not have any codes if there was a problem with the MAS and to tell u the truth i might have touched it iam not to sure

 

If I understand correctly..... and I seldom do.... but I believe if you touched the MAF it could be giving you fals readings... the MAF is a tuchy little bugger and the oils off your skill could confuse it a bit

 

iam still lost on this problem

i just some of my own tests and i learned iam burning 34.5L/100km which is way high and if the car is cold it runs nice untill it warms up alittle.

 

I was reading one of the threads here a while back and if you did touch the MAS you will need to clean it.. do a seach see if you can find where it tell you how to clean it

 

Hey guys,
Remember that the cold air filters carry in the element a small amount of oil , sometimes too much is put on at the factory and the excess oil gets sucked out into the air way which comes into contact with the air flow sensor throwing it off and causing over-fueling ..... you should "at the worst" get 12.8/100km and that shuold only be in the winter when it's realy cold.... try spraying some carb cleaner at the element but not too much...then again? I'm not sure if that might be too harsh....find out first from a qualified mechanic... but any which way I thing that sensor is contaminated.

 

Did you make sure to install the mass air flow sensor properly? If you installed it backwrds you will have all sorts of problems.
