Just came back from the garage with a couple of problems and wasn't able to diagnose in such a short time. I put my maf back in and am getting a p0103 code. Put it on the solstice pro and at first it showed that the maf wasn't reading anything. He checked something else and went back and then the maf was now reading. I also have a p0343, I replaced it a few years back after the cam swap and that lasted a couple weeks then it was back on so....F it. With that code, the same problem, the scanner at first showed nothing that all of a sudden it was showing that the sensor was reading correct. He looked at the vacuum and at idle it was showing 30.5" of vacuum. He says it should not be that low. So we hit the gas and that number didn't change. There is also a noticable missfire but was bringing up no codes. You could hear as well as feel the stumble. What could all this be releated to? I have checked all spark plugs and they look good. Could my computer be going on the fritz? Also according to the scanner, both codes popped up at the same time by the counter. Not sure what to log but here is a log from today. I could feel the misfire bit nothing registered.
