I am still trying to run down all the codes after the motor swap. The two I am having trouble with are codes 66 and 98. I know 66 is the MAF but I went trough the surging idle checklist and I think I just had a loose pin on the computer (#9) tied to wire C on the Maf harness I believe. Anyhow I think its ok now. However I also have code 98 which the book says is a hard fault in the computer. Any ideas guys. I tried searching but the search needs 3 letters numbers etc and it keeps coming back with every post with 'code' in it. I also have a code for secondary fuel pump but I don't think I ran the wire over when I did the mass air conv.
