Good afternoon. I am reaching out to see if any of you have seen the same issue I am having. I have a 1995 NAS D90. Rebuilt the motor with a stage III RPI Engineering 4.6 six years ago. Since then I have added 20K miles and within the last few weeks I have had the check engine light come on and the computer places the engine in “limp” mode. When I look at the OBD reader (under passenger seat) I am not seeing any fault codes.
