2003 Toyota Sequoia Limited 4Cyl4.8L - Engine
The truck will start and then stop a second or two later. It then will start and run the second time I start it.
After starting on the second try it does idle very low at times. I changed the fuel filter with no change. I then pulled the codes P0101 and P0102 so I changed the mass air flow sensor with no change. I then pulled codes saying all four oxygen sensors are bad. Could this be the source of the problem? Should I change 1 or 2 just to see if theres any change, there expensive! Any ideas?
