Need some opinions
I have an 09 Base and am having some troubles. Went for a drive and the engine light came on around 80mph and the car wouldn't stay running at stoplights. The book refereed it as an exhaust malfunction or engine trouble something like that. Plugged the code reader in and got a cylinder 2 misfire P115c, and P0328. I switched 2 and 4 coils to see if those were problematic and still got a cylinder 2 read. I reset the codes and now I just get the knock sensor code and it barely runs. Any thoughts?
Symptoms: Engine stalls after awhile Rough Idle Sounds like a pulley may be loose (rattle not squeak). |
What does the 2 cylinder spark plug look like?

I haven't pulled the plugs yet, I am going to do that tonight to check for oil or carbon. I did just replace them not too long ago at around 97k. I have 104k now.

2 and 3 are looking similar. Not surprising. 1 and 4 share the same exhaust route and 2 and 3 if you look at your exhaust manifold. Both are probably fouled a bit more than the 1 and 4 ports. I'd clean those plugs if they are relatively new. Any oil on them, it doesn't look like it? When I was cleaning my exhaust and intake ports the ones that shared were about similar in build up. When your 2 intake is open your 3 exhaust will be closed and visa versa. Same happens with the 1 and 4 cylinders. The first time a few years ago I only cleaned the intakes. While the engine ran a bunch better a slight ticking sound remained. This time I cleaned both and no more ticking sound. Just my two cents. See what happens if you clean the plugs first. Listen to the engine.

Check for water pump leaks as well. I had some squeaking sound turned out to be my water pump going.
