Dont drive the car much but last time i took it out had p0101 code.. maf sensor.. my mods are injen cai, mpx intercooler, injen upper charge pipes, mpx catless dp, and mpx exhaust.. the car is also tuned.. have had these mods for over a year and no problems.. so i did have a brand new maf sensor laying around.. tried changing it and cleared the code.. drove for about 20 mins the code didnt come back then when i restarted the car it came back on.. this happened a few times.. also i dont think its a boost leak because i am holding full boost i did order a new maf connector but any ideas of what else it could be before i change that.

 

Actually you can still have a leak and hold full boost. Its kinda like a evap leak it could be a gross leak or a small leak and finding the small leaks are a pain in the butt. Just leak test it to be sure

 

It sounds like there's probably a leak some where Mike. When did you start having issues?

 

about a week ago its been sitting since summer and when i was driving it i never had any issues but the last few times i have used it i threw a code for an o2 sensor.. changed the o2 sensor and it was fine then the next time i went to use i had the p0101 code so i was hoping it was an easy fix.. but other then that the car has been great since you tuned it seems like the issues started after the car sat for a while

 

yea i was just hoping it was not a boost leak but definitely looks like im gonna have to test it

 

Yeah best way to find out. Good luck

 

Yeah I would check the system for leaks man. Hopefully no mice possibly got in the engine bay with it sitting for so long.

 

Happen to be using a ZZP MAF harness?
The wires tend to come lose and the plugs wiggle.
I had that code, took out that harness, and just ran the OEM connector to the relocate and it cleared the code.

This is only if you have a relocate tho...

 

so i was wrong the code is actually p0100.. here is exactly what is happening.. i have full boost i can clear the code drive for as long as id like and it wont come back on till i restart the car.. i checked the charge piping everything seemed tight, checked the welds on the intercooler everything looks good, i have the injen cai checked that everythings tight, cleaned the maf, cleaned the map sensors .. i dont have a compressor to do a boost leak test so i tried checking everything visually and everything seems to look alright, but with the code being p0100 and not p0101 does anyone have any suggestions im trying to get this fixed asap because i need an inspection in february

 

Replace the MAF. It's 44 and free shipping on amazon for brand new Oem.

 

Here is an idea https://www.cobaltss.net/forums/2-0l...-p0100-252403/

 

Did that already

 

Saw that as well hoping thats not it to buy a ecm wouldnt be the end of the world but to lose my tune would suck
