Message hey so i need a little help, real quick ill fill you in..
got my z with bad motor, swapped motor from a 93 j30 that was an auto trans and just note my Z is an 89z32 and its a stick.
so did the swap had little problems here and there but got it done, yet its seems to be running lil rich. After new cats,o2s plugs pvc's temp sensor and 2 injectors that were close to out of range im still a little rich, ecu test 55, codes all clear. I do have the det bypass. It only fails the co2 part of the test, could it be my ecu? maf checks out could it still be bad? egr checks out aswell, checked plugs and wires. Im running out things to try lol, Also it seems like its not letting all its hp out, sluggish or being held back feeling,anyways let me know if you have any in put at all,thanks very much sorry for long post just filling everyone in...
