Was wondering if anyone can help me , car runs good but after every fill up of gas car runs rough till i hold the gas down then it will clear up but in the same time code P2187 system too lean at idle bank 1 comes on.

i have done a smoke test for leaks and there's no signs of leaks everything looks good, ive changed the air fliter ,spark plugs as well.

after clearing the code p2187 the car will not send out code again and runns just fine, only after i turn it off and back on again it will pop up but it wont run rough only at fueling..


someone help?
