Have you used an after market air filter? I am concened about your oil conditioning getting your sensors dirty.
Expert:  Danny replied 7 years ago.
this is just a question before we talk about your codes
Customer: replied 7 years ago.
is origal air filter and oil is clean i a master tec with kia
Expert:  Danny replied 7 years ago.

so both of these codes are related to your fuel trim banks and it is suggested that the fuel pressure reg is were to start and in worse case senerios the injectors. So a fiel pressure test in in order.

were do you get the inf because i check on all data and michell
Expert:  Danny replied 7 years ago.
As you know your codes are not in alldata and mitchell as i already checked there. I searched JA achieves and googled it. There is a reference to a transmission code of the p1192 but i dont think it aplies. If you look at a code chart that list all codes for obd1 or obd 2 you can find them also.

i check on goggle and they wher saying to check maf
Expert:  Danny replied 7 years ago.
Thats why I asked about the air filter. you would want to check the connections with a wiggle test and maybe clean with carburator cleaner and compressed air and see how it does. I think if it was the maff it would be the maff sensor code. which is 171 or 174
