Why does the check engine light come on after 55 to 60 miles on a 1989 Chevy S-10 Tahoe Blazer when you have replaced almost everything?

You don't start replacing things when an SES light comes on. GM OBD code readers are inexpensive and will save you time and money. It is also possible to jumper two of the connector pins together to read the code. Only then will you know what is truly malfunctioning.

YES, However, the heads are different on the 1996. they are the most sought after Vortex heads..everything will bolt right up and run great.

This is something that will drive you nuts. We had one that almost DID drive my friend nuts over. There is no "check engine" light, he replaced everything related to the engine, and it's control devices, and at the end he was ready to start yanking wires. It's symptoms almost mimicked a vacuum leak, but at other times it would run just fine. Change the fuel filter first. This is the least expensive. If that doesn't correct the problem, and if everything else has been maintained, then I would say replace the map.
