Hi All, This may be sound kinda dumb and harder to explain in an answer but could anyone tell me what happens inside the CPR once you start the car? What do the electrical connections do to the metal bar inside? The cone shaped thing with the stem and the springs on it? Can anyone explain it? I like knowing how things work. By the way, if you have a car that has a lot of miles, sat for a long time and then started up or anything like that you might want to pull the fuel lines off and see how much crud is on the screen in there. I was surprised at how much I had on mine. It is relatively easy to take apart and clean. I have 39,000 on my car and my tank was clean inside when I put the new fuel pickup in last year. Also thanks for those who responded about the oxygen sensor. I got the old one off and a new one on now. All it took was a stubby 22mm wrench, a pipe, and a sledge hammer. I put the wrench on, stuck the pipe in through the engine compartment onto the top of the wrench and hit it with the sledge. Busted it free the first hit. Some people probably just cringed didn't they? It worked and didn't hurt anything, that's all that matters.
