Well my cel went on the other day and I checked the codes. It turned out that it was the knock sensor and the engine coolant temp sensor. Could this be what is causing my problem? One problem is that when I was just cruising I popped it into neutral because I was approaching a stop light. The engine stalled out while I was rolling. Thank god it started back up again. The other problem was when I was cruising in 5th, I took my foot of the gas and I felt a stumble, then when I put my foot back on the gas it stumbled again. Should I replace the sensors?

 

The coolant temp sensor is causing your stumbling and stalling problem.

Replace both sensors.

 

I had this exact problem...same codes pulled on my car at the same time about 3 months ago...I had to replace both of them....lukily, the engine coolant temp sensor is very easy to change and cheap...the knock sensor on the other hand....

 

Ok thanks guys, I'll have them both replaced.
