Anybody have a link to a code 41 service manual chart...I have one for 86 maf but need a sd (map) one. thanks

 

the manual i have says its a cylinder select error, probable cause-terminal d3 of the ecm must be properly connected to engine ground for a v8 engine-disconnect the ECM C-D connector and probe terminal d3 with a test light connected to 12 volts. if it comes on,the terminal connection is faulty. thats all it has ,hope this helps,jimmy

 

that helps quite a bit...i'll give it a try tomorrow. Thanks Ken
