The thing is, whatever the carb cleaner did caused me a lot of problems. The car accelerated fine at low rpms but by the time I was in high gear and at about 3000 rpm the car felt like it had nothing left. So I thought it may have been a problem with the secondaries on the quadrajet being dirty or maybe not jetted properly. But besides that the car ran good.
Now, after adding the carb cleaner, it runs terrible. Sputters badly and hardly pulls. Whatever the carb cleaner did, it messed something up.
Taking the fuel line off is a good trick. I also do have a wideband AFR I could hook up when I get a chance and get a real reading to tell me what it is doing. But obviously that carb cleaner did something so I was trying to find out what.
