I have been told its a vacuum leak and have search high and low and every nock and cranny and cannot find any vaccum leaks. Furthermore, my 3.0L ff engine spun a rod bearing last week, so I yanked it out and put another 3.0 out of the salvage into it with only 120000 miles give or take...and wouldn't you know it...the same darn code pops back up after clearing computer. So, this leads me to believe its a faulty O2 sensor on bank 2 upstream. I replaced it and cleared computer...same damn code came back a few miles later...I though hmmm, I'll change the inline fuel filter...same code came back. There is only 2 vaccum lines that I found that go off of the motor to an external place on the vehicle...the fuel vap line that goes to fuel tank and the 2 vacuum lines that go to your vacuum resevior for your heater and a/c crap inside the truck...every other vacuum line is on the engine itself and was replaced with the salvage engine...so, what the freaking crap is it? I am at my wits end and am getting frustrated. There is only 3 other external things that I see it could be...the MAF sensor, the intake air temp sensor, or the other 2 O2 sensors...I have suggested the MAF to people and they say NO WAY in hell is it that, its a vacuum leak! I have checked and checked though. I've used starting fluid, soap and water, and propane and CANNOT find a vacuum leak. I am sorry for this book long story, but I just wanted to give as much detail as possible and explanations of what I already did. What is you guys ideas? Also, fuel milage is horrible...like 9 or 10 mpg...
