Recently my car has been starting hard after it gets warm. The other day it began to lose power and then finally quit all together. I got a "service emissions" reading on the dashboard indicator. The fuel pump runs, the filter is good, and the fuel rail is getting gas. I got an obd2 reading of p0325(knock sensor malfunction). If I spay carb cleaner in the air intake it will fire and run for a very short while and then just dies again. Can you help. Thanks. Steve

You say the fuel rail is getting gas, but is it getting pressure? The pressure at the rail should be around 40 psi, If it is, you will need to check that you are getting injector pulse. The fact that you can get it to start says it has spark. You either have fuel supply, or fuel delivery issue.
