Hello again. I just got the malfucntion display again so thanks to this forum, I managed to read the code with my old OBD-II reader. The codes were P0170 and P0173 which are Fuel Trim Malfunction Bank 1 and Bank 2. Any suggestion of where should I start looking? If both came bad at the same time it probably something involving both (vaccum problem or else). The car behaves within normal limits so not sure where to start.

Another issue is the fuel gauge is shutting down all the time, it just stop reading the fuel level. This had been like this since I got the car in 2005. Not sure if it is related but read something about the gas tank cap not sealing well causing the Check Engine light to come off.

Any suggestion are welcome. I read something about the adaptation of the fuel adjustment and other complicated terms I am not used to so need some education in this area.

Thanks.

Darrel
