code cleared, but check engine light wont go away
hi everyone, i've been getting p2187 & p2189 code recently so the dealership i got it from just replaced the pcv valve, air intake manifold gasket and cleaned up the throttle body. Check engine light went awayand car is running perfect.
prior to that, the car idled really rough and would hesitate when initally given gas from a stand still.
I refueled and added a bottle of techron. 2hrs into driving, after the dealership repairs, the light comes back on. i check the code with my scanner and its the same 2 codes i was getting prior to the repairs.
I erased the codes to see if they would come back again, which they probably will, before i head to the dealer again. theyre an hour and 15 min from me, so im not lookin fwd to another trip so soon. theyre doing the work for free so i have no choice.
So with all that info, the check engine light didnt go away after i erased the codes. rescanning is showing no codes but the light is still on. The scanner is even saying MIL OF. Isnt the light supposed to go off after error codes are gone?
and anyone else have tbe running lean at idle on both bankscodes?
car is running perfect after the repairs but the emmissions inspection is due and i need my tags renewed.
