LS1 swap surprises...what else is coming My harness, 02 pcm and fuel pump shipped yesterday. I had a couple of surprises. Allen tells me that my 98 model O2 sensors will not work and they may need changing due to age/use. He suggest upgrading to new 02 model O2 sensors. I have always thought they were either good or bad. No in between. Can they be worn out or not read correctly. I have all 4 off the camaro so I was counting on at least 2 being good. So thats about $200 for both. Also, I just found out I need to upgrade to a truck mass air with 5 pins.
Another $150 from GM. Does all this really have to be changed? What else am I going to run into? Any advice on these (or upcoming) surprises would be helpful. Thanks, Ryan

I don`t see a problem with a used MAF as long as it is in good condition. GMPartsdirect has new ones for $105, or try www.car-part.com or ebay for used. I would just replace the front 2 o2 sensors, and delete the back ones. The fronts are good to have but the only reason to run rear o2s is if you are in emissions hell and can only pass the inspection if you have all the factory emissions crap. You could also delete the MAF and run a speed density tune, which some people say is easier to tune but I prefer to have the MAF enabled for maximum fuel economy.
