Subject: Re: 93 LT1 intermittent miss by bogus on 2010/9/14 3:13:10 Think about this for a moment: View the ignition system as a pyramid. At the bottom of the pyramid is the coil, coil wire and ICM. These effect all items equally. In the middle of the pyramid is the optispark. It effects all things, but can effect things individually. Finally, there are the wires and plugs. They are at the top of the pyramid because they are isolated to themselves. Meaning, that the wire to plug 1 should not have a cause/effect on plug 3, and so on. Now, analyzing what you have written, the problem seems to be with #6 and #8. What do you think would cause that? A plug or wire... or the opti. I still have a couple of questions: Have you reohmed the plug wires after they get warm? I know that could be hard, but... it would be worth seeing. I wonder if the plugs are bad... try swapping these 2 with #2 and #4... see if the problem moves. Otherwise, its a high voltage problem in the opti. This will NOT throw any codes. Only codes 16 or 36 will appear when there is a problem with the opti side, not the high voltage side. |
