How do you diagnose a code 41 in a 1992 3 liter DOH Cam?

The code 41 can refer to several things....To begin with, check the resistance on your injectors. You may also want to check several other solenoids, TCL(traction control) and purge solenoid. There is a website Diamanteowners.com and you should try a search on your issue as an answer is probably there.
