I saw there was a few posts similar to my issue but not the exact same, I have a 2007 supercharged cobalt and i put a takeda cold air intake on it, 2 days later a check engine light came on and now it is running horribly. the car has a really bad misfire, slight trouble starting, bog and ofcourse the C.E.L. I have 3 codes, one says its running lean, one says i have a random misfire, the third says its a mas air flow sensor. I cant remember the codes for sure but i believe they were 101, and 114 but im not 100% on that. if anyone has had these can you help me out

i was told that putting a new map sensor and mass air flow sensor will fix it but if its caused by my Cold air wouldnt it just come back?

i cleared the codes with a reader and it did help the misfire but it came back along with the check engine light.

Thanks guys!

 

Not trying to be a dick, but its your intake messing everything up, put the stock back on

 

Any other advice?

Thx

 

The SS/SC shouldn't have issues with the intake. You MAF might need replaced or cleaned though.

 

the ss/sc will have problems with an intake change it needs to be retuned or stock intake put back on

 

First I've heard of that. I know the SS/TC is super picky, but I hadn't heard that about the LSJ.

 

Depends on the intake for the LSJ...but they do mess with the car.
