Question about 2006 Subaru B9 Tribeca
I have a Subaru Tribeca that is running really rough. I am getting P301-0306 codes so it is misfiring on all cylinders. I was told it was bad gas and been driving it and after 5 tanks of gas and putting seafoam in it twice, it still has the same problem. And here is the weird part that will probably help solve the problem. My on car info is telling me I am getting 35 mpg (and I know that is not right because usually it is 22). My Tribeca has 177k on it and the engine has had to be rebuilt about a year ago and I had to get the plastic guide replaced on the timing chain about 4 months ago.

What you should check first is the spark plug for the #1 cylinder and see if there is a white film on it this would be a sign of a coolant leak which would cause a problem with the O2 sensor

You wouldn't expect these things to happen in a brand new car! But sometimes its good for the manufacturer as they can modify parts and launch field fix programs or recalls. For you particular case I think you should ask the dealer the results of the scannings and post it here so that we can use the information you provide us to better our services and knowledge.

SOURCE: 2006 subaru B9 Tribeca Error 66
Hello, I know exactly what your talking about! and why no one else did... The error code is being displayed on your trip/odo LCD screen at the bottom of your right gauge pod if I remember correctly. Only, it\'s not Er 66... it\'s (Er bb) which is a malfunction with your vacuum pump system. I truly hope this is the same concern you are asking about, if so I am happy I could help. If it is a different problem please let me know so I can look into this matter further. I\'ve added an "error chart guide" so you will have proof this time when/if you decide to return to the dealer... Good luck!! and I hope this info helps...(subytech1)...

Now I am really depressed. We thought we have a change from driving Honda and Toyota so we decided to buy a new 2009 Tribeca. My first oil change for this car was 1800 miles, after breaking in. I replaced it with 7 qts of Mobile 1 Full Synthetic. Currently, the car has 8900 miles, that is 7100 driven; unfornately, I just filled 3 qts of new Mobile 1. Luckily, I check!!! Is this normal for Tribeca? If so, this is the worst investment of a lifetime. I won't ever buy Subaru again or recommend to anyone!!!
