So my check engine light came on my truck today, have only had the truck for about 2 weeks.
It's a 93 pick up 3.0 4x4. And the check engine light came on on the freeway. The truck still drives great idles perfectly, and runs like a top. Not sure what it is. I herd that you can diagnose the check engine light with paper clips? How do I do that? Or should I just buy a ODB 1 code reader?

Thanks that helped I got the check engine light to blink but it blinks way to fast and way to long for me to even count it, I think am doing it wrong lol

 

Here's the section from the actual manual: http://personal.utulsa.edu/~nathan-b...85diagnosi.pdf

If your CEL is blinking without pause about twice per second, you have no stored codes. You might have lost the code stored when your CEL came on if the battery got disconnected (or the EFI fuse pulled).

 

I figured It out, kinda easy. Something's wrong with my egr system. Cause it's an egr code.
Thanks guys!
