I have a similar code, but mine is system too rich...

17537 - Fuel Trim; Bank 2 (Mult): System too Rich
P1129 - 35-10 - - - Intermittent

Should i check my vacuum leaks also, or for me my maf and/or o2 sensor is bad? Btw i have a 2.8 B5.
Thanks

 

I changed three vacuum lines yesterday and the car runs great. (under manifold to fuel press regulator, under manifold to combo valve for 2nd air, and under manifold to front manifold) Will go to AZ and get the CEL cleared later. I quit before changing the longest line, from the intake manifold around front and down to the mech recirc valve. I was just worn out from the first three, which had kinks and looked the worst. PITA under that manifold. Lower back pain, bent back thumb nail, antifreeze leaking out of open lines, etc, normal project under the hood.

And, how do you break those one time only metal clips off the lines? The ones I couldn't get to to cut with wire snips, I was able to work them off with a flat screw driver, but was afraid I might break the nipples. I hope this does it and I don't have to buy and change the MAF.
