My '83 california blazer has the E4ME feedback q-jet on it. The wires going into and coming out of it control/recieve info from the mixture control solenoid (M/C) , idle control solenoid (ICS) and throttle position sensor (TPS). Now for my question. The carb sucks, it a has a flat spot the size of california in the throttle and dies the first time you start it up in the mornings. Theoretically, could I replace it with a edelbrock preformer q-jet #1904 non feedback? The problem, if any, would lie in the computer losing it because it would not be communicating with the carburetor. But would this affect the other systems the the computer controls, or just make the check engine light be on the whole time? Even though it still needs smog checks, it would only take me a little while every 2 years to switch back to the feedback carb to pass the check. Has anyone tried this?
