Hi all, I just wanted to update everyone on my issue. When I put the elbow on I cleared all fault codes (p0171, p0174, and p1131) and hoped my problem would be solved. 3 days later the "service engine soon" (ses) light came back on. This time the only code was p1131. My research led me to believe that the vacuum leak had been fixed by the new elbow (no more p0171 or p0174) but that I had a problem with the upstream 02 sensors (p1131). So I ordered two new 02 sensors from Rock Auto in Wisconsin. Interestingly, the two sensors together only cost $64.70 Canadian, including shipping right to my mailbox, whereas I understand they would have run about $70 each, plus 13% taxes, at Canuck Tire. Go figure.
Anyway, I had to borrow an 02 socket from my brother to try and get the old ones off, and before I got the chance, the ses light went off on its own. That happened about six weeks ago, and it has not come back on. So, crossing my fingers: a) my problem appears to have been resolved by the new elbow alone, b) I have two brand new 02 sensors sitting on a shelf in my garage! However, if my problem is indeed licked, considering that I wrestled with it for over a year, all the while fearing a more serious issue like lower intake manifold gaskets or something else expensive, I will positively state that that $64.70 is the best money I ever wasted!!
