I wanted to start a discussion, I hear all the time that the carbs have idle issues,that seem to be unfixable, how many people know that the carb has a separate temp sender on the block just like the EFI? I was looking through the service manual, just because I'm glad I don't have all that crap anymore, and I had forgotten all about it. Everyone knows with EFI the gauge has one sender, and the computer another, well the carb computer also sets parameters such as idle,mixture etc. based on coolant temp. where is it? it's almost impossible to see, but it's screwed into the block under the intake manifold, with everything in the way, most people wouldn't even know it's there. I wonder how many have failed and if this is the root cause of all the idle issues, The carb computer is a lot more sophisticated then most people think, it really is a computer, so give it a bad critical input, and you are going to get bad outputs, the difference is the carb computer has no check engine light, so a failed sensor gives no indication. These sensors are a common failure on FI engines, so I would assume the same on carb engines. It would be interesting to see if it's the same sensor as the FI engine.
