问：汽车运转粗糙，所以我发现这是一个错误的ICM。改变了这一点，现在汽车甚至都不会启动。

Hello, thank you for writing in. With the new module you installed, there is likely some other issue with an input to the computer. Either that or the computer itself is having issues. You can only test the computer by testing its inputs vs. its out puts. If it looses connection over the computer, you know its the component to blame. You will also want to check all of the wiring and make sure the terminals are all clean, dry, and tight. If the entire ICM system and computer checks out, then you want to turn your attention to the intake air sensors, and having the vehicle re-scanned for codes if possible. The last recommendation is to verify the repair of the new module that was installed in the first place. Make sure it is the right module, and is communicating effectively.
