Ok so im getting these codes randomly. I installed a cold air intake on the cobalt. A few days went by the car was running fine. now im getting these codes and having a helluva time figuring out what the culprit is. my first thought was the cps sensor was goin because it was acting just like all the others were on here. now i feel like it is the air intake and something to do with that. has anyone experiacned any problems putting a ccold air intake on a ss/sc model. i bolted it on switched the sensor and even replaced the sensor. cars runs good then outta no where stutters and goes into reduced engine mode. after reading the material that coblast sent me(thanks great info btw) im thinkin the car is getttin too much air and messing with the scip and the tb sensor. does this sound accurate ive never messed with superchargers onlyy turbos so bare with me here. this scenario would also put the car into reduced engine mode. it was an ebay intake dont member the name. i have replaced every possible vacuum line i can see cause it almost felt like it had a leak somewhere. today the car will stutter and struggle to produce boost and no cels and then after about 3500 rpms it will hit about 10 psi. granted it is 104 here today but why is it bucking and not throwing a code? im gonna start over and put the stock intake on and drive it around see what happens. any similar problems or suggestions would be wonderful. thanks.

 

The intake is probably causing the airflow to be a little too turbulent or leaking for decent MAF readings. The P0068 is because the airflow sensors aren't agreeing with each other's readings and the P1182 is from the blower's inlet pressure sensor reading being too varied from the measured airflow of the MAF and others.

A poor flowing air filter can also cause the same problems.

 

As witt said the air filter,What kind is it if its a noname brand it might be either to restrictive or flow to easily.
From what I under stand the ebay cai are not designed right and alot of people had problems with them throwing codes.
I remember one guys solution was to cut off the restrictive peice or something to that effect.

Compare your cai to a injen and see if there is a differencec size wise on the ends etc.Never had a code with the injen .

 

I also have a P1182 that makes my car go into limp mode if I get into boost. Have tried several things, nothing worked yet. Its not the filter, anyone with a solution?

 

ok makes sense. now i went for another ride to get some gas in it. i took the head light assembly out tightened every connetion on the intake left the after market intake on. car hits a wall in first cant not boost cant floor it nothing. no cel's no reduced power mode (feels exactly like it however) then hit about 3200 rpms cars run like a raped ape again. i was out on some back roads full boost all the way through second then all the way through third. but in low rpms in first and second it stutters and hesitates but in second its boosting to about 9 psi then 3k rpms and she takes off. should i replace the cone filter with a name brand or revert back to stock intake. the thing that really confuses me is no cel's or reduced power mode and i havent done hardly anything. but in first it runs just like its in reduced power mode if i try to hit boost at all.

ok sounds good. ebay intakes = fail for forced induction im thinkin. sscobaltss do u have an intake? where in phx are u lol we can fix this together.



this is the intake... looks identical to injen and xtc....

 

I live in north phoenix.. Yes I have a K&N, I have had the intake on the car for about 2-2.5 years and the code showed up a little over a year ago. It was not too bad in the beginning but got gradually worse and worse, I could (in the beginning) boost without it affecting anything, but now I boost and it goes into limp mode right away.

 

Check for this ,1)Restrictions or debris in the SCIP sensor vacuum port.

2) Any damage or fractures to the SCIP sensor housing

3) A missing or damaged SCIP sensor seal



I would think this would be by removing the scip sensor and taking a good look at it or maybe cleaning it some how.
Could be full of oily crap from the pcv hose.

 

Is the SCIP right on top of the blower? In view when you open the hood?

I have cleaned it before and nothing worked, I just didnt really check if it was cracked or ruined somehow.. guess I should do that..

 

Yes the Scip is located ontop of the SC.
Did you check the connector for it as well,take a good look at it with a flash light.
Wires going into the connector as well.

 

Ok will do. I did check the connection and everything before, I just didnt look at it too closely.. I will do that and let you know.. thanks for the help, hope it works

 

ScCobaltSS did u ever get your issues fixed? i went back to the stock intake and still having problems.... im at a loss i just want to light this car on fire and push it into the grand canyon. im confused about the MAP sensor and SCIP sensor are they the same thing? the dealership said the map sensor was on top of the supercharger and i was told on here that the SCIP sensor is ontop of the supercharger????

 

My friend just had this problem,i checked the wires going to the map sensor and some of them were sliced,i fixed the wires and everything is ok now.

 

Never did, I checked all the wires to the SCIP and the SCIP itself, which is on top of the blower from my understanding, and all was good.. Where is the MAP?

 

i dk were taking it to a dealership let them mess with it... this car is a nightmare... once we diagnose it i can help you with yours if you'd like... ill let you know after tuesday...

 

Ino this is a old thread but I put two new vac lines on yesterday at work and it threw this code this morning and kinda freak me out ... any suggestions

 

Double check you got them all in the right place or clean the MAF or scip
