P2187

So on way back home from work the car throws a cel, just normal driving conditions. Got home busted out the obdII sensor and read the code, it says:

"P2187 System Too lean at Idle Bank 1"

has anyone had this problem and know what the problem is in detail?

check for leaks in your intake system (specifically after the MAF, likely pre turbo)

Yeah, the specific problem is that the LTFT is to high(+) at idle. The LTFT too high is caused by the fuel mixture reading too lean on the WBO2 sensor. The too lean condition can be caused by any number of air leak locations after the MAF sensor. You must locate and fix the leak...
