I have a 97 blazer that is driving me crazy. It misses and runs very lean. Ive tried a new fuel pump, crank sensor, cam sensor, throttle position sensor, plugs, wires, cap, rotor button, and coil. Nothing helps. My question is this. Can the current setup be changed over to a carburetor system? I noticed summit racing has a carb intake. Can the distributor be changed to a vacuum advance distributor? Im tired of messing with this engine the way it is. Thanks

 

is it setting off any dtc

any indicator lights on the dash?

 

i have never heard of a carb intake for a 97 4.3L but im not saying they dont make one. if you find a whole setup let me know cause i would love to swith my 96 over to that. im not a big fan of fuel injection anyway. in regards to ur question about the vacuum advance distributor... im sure if they make the carb intake setup, i would be willing to bet you can do that.

 

The spider injector could be leaking
