Question about Chevrolet Blazer
These engines are notorious for a leaking lower intake gasket, as well
as the fuel injector assembly being faulty. You may have a fuel pump
going out, you have to put a fuel pressure gauge and/or a scanner on it
and see what your fuel pressure is and if you have any codes.
Test with pull the plug wires off the distributor coil one at a time and see if theres any greenish build up on the tips of the coil. When bad wires or a coil gets warm they will lose the strengh of the spark and you will lose power. Look into a weak coil pack or a bad ignition module.
On the carb there is a sensor/solenoid that richens up the mixture for cold start purposes. Its been a while since i have worked on a tbi engine so i cant remember where it is at but look for a sensor or a solenoid (its not the fuel injector solenoid/s) on the carb.
