I have read through most of the problems that I am having, and I still have a few questions.

My 94 S-10 Blazer with 4.3L Vortec is still having problems. Several moths ago, I took apart the intake manifold and had it cleaned, replaced the gaskets and the "nuts" into the CPI wich had a hole in one part.

When the problems first occured, it would run fine when it was cold, but as it warmed up to operating temp, it would just die. With the help of some starting fluid, it would start again and run at a high RPMs, but would die at low RPMs. I have replaced the fuel filter, fuel pump, and sending unit so far with the same problems. I took off the EGR valve, cleaned it, and replaced it with a new gasket. The engine ran great for about a day, then the problems started again. I have ordered a new CPI to replace the old one, and I would like to know if that may solve my problems. Any feedback would be great so I can stop replacing everthing!!
