p2187
Hello. 2005 Boxster "S". I replaced the A.O.S and Air Mass s. Replaced spark plugs. The check engine light is still on so I picked up a harbor freight tester that claims to be able to clear the error message. I Hooked up the tester and it claims 2 issues. It states a P2187 $11 generic. that refers to "system to lean at idle bank 1". The plugs I pulled did look pretty lean on cylinders 1,2,3...I read the tester manual and it states that if I clear the codes I will lose the current fault data stored. For this reason I opted not to clear. I worry that If I clear and all the codes do not clear .....Some one that i take the car to will have difficulty reproducing the data....the computer cycle thing...... The question is.....how to I address the p2187 posting.... Thanks bob
