Need help...check engine light - Diesel Forum

greasypig · 11-15-2005, 09:27 PM

I need help. My check engine light came on twice today. The truck shifted from 2nd to 3rd each time. After a short while the light went out. During the time the light was on I switched back to dino for a few miles.

I have run 50/50 for 6000 miles and have run 100 wvo except for purge for 2000 miles. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

2002 7.3 with 127000.

This is really the wrong forum to post this, but the VERY FIRST thing I would do is to find someone with a ODB-II scanner and find out just what code your truck is throwing.
If you don't know that, there is no way to diagnose your problem.
Good luck, and you may find out that it is in no way related to your WVO...
