1993 S10 Checy Blazer Check Engine Light

[husky21]

When I start up my car the check engine light comes on and after 3 minutes it turns off. As I am driving it does the same thing. I was told that a 1993, S10 Blazer does not have any memory to store the error codes. Any help thanks

It definitely has memory & the codes can be read.
You can do it yourself. or take it to autozone or advanced auto & they will read it for free.

When my truck was doing that it was the knock sensor.
But get the code read.

X3 But autozone or advanced auto around here will not read codes on first gen.

Here is the How-to on checking the codes yourself:
