Hey guys. I recently did a MAF conversion and H/C/I. I've been having some issues with idle surging. I was told by some pretty knowledgable people that my O2 sensors were no longer the right ones. They said that MAF cars use a different one than I had on my SD car. Before I go and buy new O2 sensors at almost 100.00, are they right or do I have the correct sensors? I looked it up on Autozone's website and they show the same part number for an 87 SD car and a 93 MAF car. Please help me out here.
