I have a bunch of intake related codes. I replaced the MAF, check the engine light went away. Brought it to a shop to install need radiator fan, and about 2 hours after picking it up engine light came back with same codes, so I replaced the MAP and codes went away for a half hour then came back. When I first start my car is fine but after an hour or so it has rough idle, and really bad acceleration. The car listed above has 1.4 turbo with ZZP intake. Any suggestions as to what is causing this?

Codes:

P0097

Intake Air Temperature Sensor 2 Circuit Low Bank 1

P0099

Intake Air Temperature Sensor 2 Circuit Intermittent/Erratic Bank 1

P00F4

Humidity Sensor Circuit Low

P00F6

Humidity Sensor Circuit Intermittent/Erratic

P0114

Intake Air Temperature Sensor 1 Circuit Intermittent Bank 1

P2199

Intake Air Temperature Sensor 1/2 Correlation

P2230

Barometric Pressure Sensor "A" Circuit Intermittent/Erratic

I suspect these are all going to be related but clearly, they are all different sensors or systems. So, the way to figure these things out is to pick one of them and run through the diagnostic and repair it. If it fixes all of them then that is a bonus. If not, then we can move onto the next.

Here is a guide that will help with this type of testing:

I am attaching the info below on the P0097 which is where I would start.

Please run through this testing and let me know what questions you have. However, I suspect this is either a wiring issue related to the 5-volt reference or a control module issue.

Thanks
