1994 4.3 with CPI way to much gas
I have 1994 s-10 with a 4.3 w motor all stock. Can the injector stick open on these motors or what would cause it to fill the oil with gas

Either the lines inside the intake are bad or the regulator is bad. If the drivers side of the intake is clean its the lines if the passenger side is clean its the regulator. In all honesty the parts have come down so much in price that its better to do both at once.

I agree with above. I guess your talking about the CPI vin W? Those spider units go bad after about 80,xxx miles, and you need the "nut kit" also. Really, it's the fuel lines, no idea why they call it a nut kit. The real fix, is to pull it out and put in a LSX.
