I have a ‘94 Chevy S10 Blazer, VIN code W. It starts to lope if I let it idle for a while. I put a new spider and checked for any leaks. Any help would be nice. Thank you!

The spider was a good thing to change. This could be a simple vacuum leak or it could be a catalytic converter stopping up. You might need to have a pressure test done at the fuel rail and make sure you have a minimum of 50 PSI at the fuel rail.
