Codes 12,25,26,52 Help!!!!!

Core 12 check your distributor connection or read wires from the ECU plug and read the loop through the distributor but for that one I would clear the ecu and see if it returns.
The code 52 could also be the connection, re-check that before doing the costly relacement.
For the 25 and 26 its a little more serious. When I had that I ended up burning my rings because it was running too lean. My problem ended up being the O rings on the injectors. They were pinched distorted and not soft and pliable which allowed air to go by and lean out the mixture. I made a post on it before with pics, just do an advanced search for code 25 26 and my nick.
