So my car keeps saying engine power reduced for the last couple days. Car has no power once it happens and it sounds like ****, I pull over and start it a couple times and it will be back to normal and sometimes run fine for a bit and then do the reduced engine power again.. I cleaned the maf sensor, throttle body, the sensor on top of the supercharged, checked the connections on the throttle body and it still does it. I dont wanna have to bring it to a dealership if I dont have to. I got 5 codes

p0171 system to lean

p0069 Map-Barometric pressure correlation

p0121 Throttle/pedal position sensor/switch a circuit range/performance problem

p0068 Map/maf throttle position correlation

p2228 barometric pressure circuit low input


If you guys have any ideas please let me know!

 

Sounds like the car cant get the position of the gas pedal to correlate to the position of the throttle so it panics.

This is a complete shot in the dark, but try disconnecting the battery, manually closing the throttle all the way, unplugging the throttle, and then putting everything back together again before re connecting the battery.

 

I remember reading about a few people that had the same problem as you a few months back. They replaced the throttle body and the problem was solved

 

Im just worried about buying a new tb and that not being the problem

 

my redlije did something similar but I equated the problem to the intake tube not being all the way connected

 

So I scanned my car again and now this one was added p2228 barometric pressure circuit low input

 

Have anyone local that you could swap in their tb real quick

 

Thats actually a good idea but I dont know anyone around here that has a supercharged cobalt, there all base models

 

This guy is selling a lsj throttle body for $60 shipped

mine did this the other day... just make sure all of your sensors are pluged in and working. i for got to plug in a sensor after i was changing my oil... made it about a mile and it hit...thought i blew it up.
